...Statistics Chapter 5 - Review - A random variable is a variable (typically represented by x) that has a single numerical value, determined by chance, for each outcome of a procedure. A probability distribution is a description that gives the probability for each value of the random variable. It is often expressed in the format of a graph, table, or formula. A discrete random variable has either a finite number of values or a countable number of values, where “countable” refers to the fact that there might be infinitely many values, but they can be associated with a counting process, so that the number of values is 0 or 1 or 2 or 3, etc. A continuous random variable has infinitely many values, and those values can be associated with measurements on a continuous scale without gaps or interruptions. Examples: 1.) Discrete: x = the number of eggs that a hen lays in a day. This is a discrete random variable because its only possible values are 0, or 1, or 2, and so on. No hen can lay 2.343115 eggs, which would have been possible if the data had come from a continuous scale. 2.) Continuous: x = the amount of milk a cow produces in one day. This is a continuous random variable because it can have any value over a continuous span. During a single day, a cow might yield an amount of milk that can be any value between 0 and 5 gallons. It would be possible to get 4.123456 gallons, because the cow is not restricted to the discrete amounts of 0,1,2,3,4, or 5 gallons. Requirements...

Basically whether the average reading of all men named Joes is different from the average reading of all Jon' or whether these averages differ from the average reading of all Marks.

Basic Econometrics

...Question 1: Conceptual Question (a) Model I: The major econometric issue is on the error term ui. The equation ui2=γ1+γ2x1,j indicates that the error term ui is related with the independent variable x1. Under the general assumptions, the error term us designed to capture ‘unexpected’ events, as such the error term should be random and the independent variable x1 is not random which means that its value if known. Therefore, model I breaks out this assumption, the error term ui is related with the independent variable x1 (not random), error term uiwill hence be not random as well. As a result, the dependent variable y will be not random which is wrong in econometrics. (b) Model II: The major econometric issue is on the error term vt. The equation vt=ρvt-1 indicates that for the pair of random error term vt and vt-1, there is linear association among them. Under the fourth assumption of the simple linear regression model, the covariance between any pair of random errors is zero, implying that there is no linear association among them. Therefore, model II breaks out this assumption, one random error term vt has a linear relationship with another random error term vt-1. (c) Model III: The major econometric issue is on the independent variable x1,i. x1,i~i.i.d(ux, σx2) indicates that x1,i is independent and identically distributed random variables. Under the fifth assumption of the simple linear regression model, it requires the regressors x1,i to...

Pokemon Ev Traing

...will be silly of us to mention EV training with mentioning the Super Training. It hasn't changed since X and Y and you should definitely complete that before doing this. So how exactly does Pokemon Omega Ruby and Alpha Sapphire make it easier to EV train your Pokemon? Let’s take a look. Basics Let’s start with the basics of EV training. As many veteran trainers know, every Pokemon is allowed 510 Effort Value points that will go into their overall stats. These points are based on what Pokemon you defeat. Each Pokemon in ORAS has a specific amount in a given stat their EV points go toward. For example: A Wingull gives 1 Speed point. Each stat is allotted 252 EV points to max out a Pokemon’s potential in that particular stat. So, back to the Wingull, defeating 252 Wingull at 1 Speed point each will max out a particular Pokemon’s Speed stat. Some simple math shows that a Pokemon can max out two of their stats with the 252 EV points allowed -- with 6 EV points being left over for whatever stat you so choose. Which stat to EV Train to its max potential is solely on the preference of the trainer...

Data Mining

...A Statistical Perspective on Data Mining Ranjan Maitra∗ Abstract Technological advances have led to new and automated data collection methods. Datasets once at a premium are often plentiful nowadays and sometimes indeed massive. A new breed of challenges are thus presented – primary among them is the need for methodology to analyze such masses of data with a view to understanding complex phenomena and relationships. Such capability is provided by data mining which combines core statistical techniques with those from machine intelligence. This article reviews the current state of the discipline from a statistician’s perspective, illustrates issues with real-life examples, discusses the connections with statistics, the differences, the failings and the challenges ahead. 1 Introduction The information age has been matched by an explosion of data. This surfeit has been a result of modern, improved and, in many cases, automated methods for both data collection and storage. For instance, many stores tag their items with a product-specific bar code, which is scanned in when the corresponding item is bought. This automatically creates a gigantic repository of information on products and product combinations sold. Similar databases are also created by automated book-keeping, digital communication tools or by remote sensing satellites, and aided by the availability of affordable and effective storage mechanisms – magnetic tapes, data warehouses and so on. This has created a situation...

Bello, Chair, Dept. of Economics The College of Economics and Management (CEM) was formally created in the 996th UP-BOR meeting, February 1987. However, the College traces its roots to the Institute of Agricultural Development and Administration (IADA)which was established in 1975, with three departments – Agricultural Economics (DAE), Economics (DE), and Management (DM), and was elevated to the College of Economics and Management from the merger of IADA with the Agricultural Credit and Cooperative Studies and the Agrarian Reform Institute in 1978. At present, CEM is composed of three departments – the Department of Agricultural Economics, the Department of Economics and the Department of Agribusiness Management. The college sees itself as a center of excellence in undergraduate and graduate instruction, research and extension in economics, agricultural and applied economics, and agribusiness management in Asia. It envisions to be an institution of higher learning that can serve as an active catalyst for economic and social transformation. Its two-fold mission is to produce graduates and future leaders with strong training in economics, agricultural and applied economics, and in agribusiness...
