...TYPE OF DATA Times Series Data A time series is a sequence of data points, typically consisting of successive measurements made over a time interval. Examples of time series are ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average. Time series are very frequently plotted via line charts. Time series are used in statistics, signal processing, pattern recognition, econometrics, mathematical finance, weather forecasting, earthquake prediction, electroencephalography, control engineering, astronomy, communications engineering, and largely in any domain of applied science and engineering which involves temporal measurements Cross-Section Data Cross-sectional data, or a cross section of a study population, in statistics and econometrics is a type data collected by observing many subjects (such as individuals, firms, countries, or regions) at the same point of time, or without regard to differences in time. Analysis of cross-sectional data usually consists of comparing the differences among the subjects. For example, if we want to measure current obesity levels in a population, we could draw a sample of 1,000 people randomly from that population (also known as a cross section of that population), measure their weight and height, and calculate what percentage of that sample is categorized as obese. This cross-sectional sample provides us with a snapshot of that population, at that one point in time. Note that we do not know based...

...John Smith C257 Task 1 Data aggregation as it pertains to healthcare is the collection of health data from individual health records that are then grouped into a collective database that can be further analyzed and used for research. This data does not identify individual patients, but instead focuses on groups of patients which are then used for research purposes such as finding linking factors that could be the cause of certain illnesses. Also by having multiple sources for this data allows more statistical validity when determining these factors. Data aggregation is not only beneficial in this aspect, but can also be used to improve consumer transparency by allowing patients access to provider quality evaluations through multiple different sources. Although data aggregation can be beneficial for future and present healthcare issues, it is not without its faults. For instance in order to have a truly unified database, it would take multiple companies and industries working together to make this happen. Also at this point the suspicion about data aggregation and how it will ultimately be used is still an issue. In an article by Regan and Randall-Lewis (2008) there is a question posed “Is data being used to either reform the healthcare system or “out think” your rivals?” which asks whether this data will be used to find health trends that will lead to the betterment of society’s healthcare or the financial gain of a company. Lastly the security risks involved with having...

...enumerations and type definitions. Naming: The variable name is the way to reference the stored value. It allows the name to be used independently of the exact information it represents. Assignment: It sets or re-sets the value stored in the storage locations marked by a variable name. It copies a value into the variable. Assignments allow a variable to hold different values at different times during its life span and scope. Although, some languages do not allow that kind of “destructive” reassignment because it could imply changes of non-local state. and Initialization: The process of locating and using the defined values for variable data that is used by a computer program. The operating system or application is installed with default or user-specified values that determine certain aspects of how the system or program is to function. These values are stored in initialization files. When the operating system or an application program is first loaded into memory, a part of the program performs initialization, finds definite values to substitute for variable values, and acts accordingly in program designs. Use the correct data type for variables in program designs. Variables are “placeholders” used to store values that have names and data types. The data type of a variable determines how the bits representing those values are stored in the computer’s memory. When you declare a variable, you can also supply a data type for it. All variable have a data type that determines what...

...them issue out change. Use of Visual Basics Visual Basic for Applications (VBA) will be used because it is a programming language built right into many Microsoft programs. This language is built on the Basic programming language made popular by PCs over the past 25 years. VBA shares similarities with other Windows implementations of the Basic language, such as Visual Basic. If you are familiar with programming in a different language (including using macros), you can quickly get up to speed with VBA. There are a few terms you should know before you start programming in VBA: * Procedure. A section of programming code, designed to accomplish a specific task, which your program statements can use throughout your program. There are two types of procedures: functions and subroutines. * Function. A procedure that returns a value after it completes its task. When called, functions typically appear on the right side of an equal sign in an expression. * Subroutine. A procedure that does not return a value after it completes its task. * Module. A named collection of procedures. You typically attach modules to specific forms or reports. You can accomplish many tasks simply by using macros. This implies--and correctly so--that not everyone needs to use VBA. As a general rule, if you can accomplish a task by using macros, do so. Macros are simpler to implement and easier to maintain. However, there are certain tasks...

...consisting of a one-dimensional and a two-dimensional array in this case would be a good way to solve this problem in a simplified code format. An array would also allow all the data the user wants to input to be stored in the program for multiple queries to be run without having to re-input the data. So this module of the program will allow the user to input all the different procedure codes billed the provider and return a units-per-patient statistic for the searched procedure code. Assuming the data that the user will input is all for the same provider, the following variables will need to be declared: the procedure code, the number of patients, and the number of units billed. Two arrays will be declared as well, one for the procedure code and one for the number of patients and units. The procedure code variable and array must be setup with a string data type since there are some procedure codes that have alpha characters. The number of patients and the number of units variables, as well as their corresponding array will be setup as integer data types. Since both of those variables are of the same data type they can be combined into one two dimensional array. These two arrays will be parallel because they will be the same size and the subscript is related (Venit & Drake, p. 293, 2011). A real data type is used to calculate the units per patient. In a real life scenario, there are tens of thousands of medical procedure codes for providers to use when billing. For this...

...DECLARATIONS & OPERATORS AGENDA Declaring Primitives, Reference Variables & data type casting - Practical Session Arrays -Practical Session Using Operators -Practical Session Declaring Primitives & Reference Variables Java Identifiers All the Java components - classes, variables, and methods need names. In Java these names are called Identifiers – Identifiers are representing the names of variables, methods, classes, etc. – Examples of identifiers are: employee_id, main, System, out. – Java identifiers are case-sensitive. This means that the identifier ‘employee_id’ is not the same as Emplyoee_ID. – Identifiers must begin with either a letter, an underscore “_”, or a dollar sign “$”. Letters may be lower or upper case. Subsequent characters may use numbers 0 to 9. – Identifiers cannot use Java keywords like class, public, void, etc. Examples of legal identifiers: int _id; double $c; long employee_id; Java Identifiers Coding Guidelines for Classes, Methods & Variables 1. For names (identifiers) of classes, capitalize the first letter of each word of the class name. For example, MyFirstJavaClass 2. For names (identifiers) of methods and variables, the first letter of the word should start with a small letter. For example, myFirstMethod Variable A variable is an item of data used to store the state of objects. A variable has a: – data type The data type indicates the type of value that the variable can hold. – name The variable name must follow rules for identifiers. ...

...Explicit Type Conversions In some cases we have to perform conversions , that is the compiler does not automatically convert a type to another . These type of conversion is called Explicit conversion . An explicit conversion uses a type conversion keyword. With these conversion keywords we have to perform the Explicit Conversion. String.Format(), creates strings by combining string values with other data types and controlling how each value is displayed. Rather than formatting values individually and then concatenating them, Format() works with a string that specifies insertion points in its text. These insertion points are then replaced with the actual values. Being a string itself, the format string can be loaded from external files and resources, allowing for flexible string handling that can be convenient when working with internationalized and localized applications. Format specifiers are special symbols that specify the way data is formatted during its conversion to a string. This topic describes frequently used standard and custom format specifiers used to format numeric and date/time values.

...of seven numbers representing the rainfall value for each day that week. Your program should output the rainfall data, including the average rainfall value for each week. 2. Design a billing summary report from a file of billing and payment information. Each record, line in the file, contains three items. The first item is a letter code indicating if the record is an order (O) or if the record is a payment (P). Next will be a string containing the customer number, and finally, the record will contain the amount of the order or payment. Your report is a summary of these data, indicating how many orders were placed and the total of the order amounts. You will also indicate how many payments were made and the total of those payments. Finally, you should compute the percentage of sales and orders. There will be no more than five records in the file. 3. Develop a program to summarize borrower fine data for your school library. The input file consists of three fields: the student number of the student, the type of item borrowed (‘book’ for reading material, ‘movie’ for DVD, and ‘music’ for CD), and the amount charged to the student for the fine. The first time you see an item type in a record, you should record that in a variable and begin to track the total for that type of item. Every file will not contain all item types, and your program should only report summary data for the actual values in the file. You should report the following summary: the item code given in the file, the...

...1. What does static variable mean? When a variable is declared to static it will be initialized the default value zero. It is local to the block in which it is declared. The lifetime persists for each and every function call. 2. What is a pointer? A pointer is also called a reference of a particular data type. But instead of storing some value it stores the address of a particular variable. This address can be initialized by using “&” operator. Eg: int a = &b; 3. What is a structure? Structure is a special type of user defined data structure which comprises of a collection of certain type predefined data types like int, char, float etc. It is an entity which comprises of many atoms. 4. What are differences between structure and array? Arrays are group of data of same data type, whereas structure is combination of entities of different data types. Size of array needs to be declared initially itself whereas structure can be done both initially and dynamically. 5. In header files whether functions are declared or defined? Inside header files the functions are defined and they are not declared. This is also a type of structure definition. 6. What are the differences between malloc() and calloc()? malloc() takes a single argument(memory required in bytes), while calloc() needs 2 arguments(number of variables to allocate memory, size in bytes of a single variable). Secondly, malloc() doesnot initialize the memory allocated, while calloc() initializes the allocated memory...
