Multi-regression Analysis Summer 2013 EC315: Quantitative Research Methods Professor Scott Sowder

Introduction
One day I was sitting in class with my classmates. Our GPA, the number of classes were are taking, ages, IQ and the amount of time we spend studying were all different. I became curious and wanted to know what effect the different variables had on the student’s GPA, if any. So I decided to a survey of 30 students with varies GPAs, IQs, ages, number of classes being taken and the time they spend studying. My hypothesis statement is that all the independent variables will have the same or no effect on the dependent variable. The alternate statement is that at least one of the independent variables will have an effect on the dependent variable. I have applied a 95% confidence level, which means I am 95% sure that I will be able to show that at least one of the independent variables will have an effect on the GPA.
Variable Identification
My dependent variable is the students’ GPA. I chose GPA as my dependent variable because it relies on the other variables.
The remaining variables are my independent variables. I chose them because they could all have an effect on a student’s GPA. Student | GPA (4.0) | # Classes | Age | IQ | Study time | 1 | 3.2 | 4 | 29 | 119 | 12 | 2 | 3.1 | 2 | 31 | 118 | 8 | 3 | 3.7 | 1 | 28 | 135 | 6 | 4 | 3.5 | 3 | 22 | 129 | 13 | 5 | 2.8 | 4 | 22 | 110 | 15 | 6 | 3.0 | 3 | 24 | 115 | 15 | 7 | 3.8 | 2 | 24 | 136 | 13 | 8 | 3.5 | 4 | 22 | 133 | 14 | 9 | 3.4 | 4 | 23 | 130 | 18 | 10 | 3.2 | 1 | 29 | 122 | 4 | 11 | 3.0 | 4 | 34 | 110 | 13 | 12 | 2.7 | 4 | 23 | 106 | 20 | 13 | 2.8 | 3 | 25 | 105 | 3 | 14 | 4.0 | 2 | 28 | 141 | 10 | 15 | 3.4 | 4 | 29 | 128 | 18 | 16 | 3.3 | 4 | 25 | 127 | 16 | 17 | 3.5 | 4 | 23 | 134 | 29 | 18 | 3.2 | 4 | 50 | 123 | 20 | 19 | 3.1 | 4 | 23 | 116 |

Significance and Advantages of Regression Analysis

...Significance of Regression Analysis In statistics, regression analysis includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically, regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed. Most commonly, regression analysis estimates the conditional expectation of the dependent variable given the independent variables — that is, the average value of the dependent variable when the independent variables are held fixed. Less commonly, the focus is on a quantile, or other location parameter of the conditional distribution of the dependent variable given the independent variables. In all cases, the estimation target is a function of the independent variables called the regression function. In regression analysis, it is also of interest to characterize the variation of the dependent variable around the regression function, which can be described by a probability distribution. Regression analysis is widely used for prediction and forecasting, where its use has substantial overlap with the field of machine learning. Regression analysis is also used to understand which among the independent variables are related to the dependent variable, and to explore the forms of these relationships. In restricted circumstances...

Statistical Analysis of Foreign Direct Investment in India

...INTRODUCTION Unprecedented globalizations have witnessed double digit economic growth resulting in fierce competition and accelerated pace of innovation. As a result inflow of Foreign Direct investments has become a striking measure of economic development in both developed and developing countries. FDI and FII thus have become instruments of international economic integration and stimulation. Fast growing economies like Singapore, China, Korea etc have registered incredible growth at onset of FDI. Though US captures most of the FDI inflows, developing countries still account for significant growth of FDI and rise in FII. FDI not only gives access to foreign capital but also provides domestic counties with cutting edge technology, desired skill sets, tools of innovation and other complementary skills. Apart from helping in creating additional economic activity and generating employment, foreign investment also facilitates flow of sophisticated technology into the country and helps the industry to march into advanced technology. A favorable business environment fostered Indian economy after 1991, when the government of India opened the door for foreign capital in the way of direct investment and through foreign institutional investors. The policies drafted to stimulate the flow of foreign capital in to India provided much needed impetus for India to emerge as an attractive destination for foreign investors. Consequently, the international capital inflows have been...

Advanced Inferential Statistics

... Understand the concepts of Binary Logistic Regression Logistic regression is essential in predicting a categorical variable present in a set of variables that are predictors. During Logistic regression, categorical dependent variable which is the discriminant function is used when all the predictors that are present are continuous and distributed in a nice way. The binary logic regression has become the most preferred data analysis method that describes the relationship between response variable and an explanatory variable that and it is usually used where a variable follows binomial distribution. Assumptions of binary logistic regression Among the assumptions applied in the application of binary logistic regression is that logistic regression usually does not assume a relationship that is linear between the dependable and undependable variables. It is a must for the dependable variable to be a dichotomy i.e. must have two categories. It is also not required that the independent variables to be an interval, distributed in a normal way, linearly related, or even have linear variance within specific groups. Another assumption is that large samples are most important in this regression because it has a maximum likelihood of coefficients of large sample estimates. It is usually recommended that one should have a linear regression of 50 cases and above per predictor. Requirements for Binary Logistic Regression When carrying out binary logistics it is required...

Multiple Regression

...Project Title: A STATISTICAL ANAYLYSIS OF NBA PLAYER SALARIES USING A MULTIPLE REGRESSION. ABSTRACT Basketball is one of the most popular sports in the world and National Basketball Association (NBA) is the most popular basketball league in the world. The NBA league is based on the United States of America and it consists of 30 teams. The NBA is so popular that the NBA finals are the 2nd most watched televised event in the U.S. after the NFL (National Football League) Super Bowl. Sometimes when we think about NBA players and the enormous amount of money they are making, we become a little jealous. It is well known about how some star players make so much money or are over-paid and yet can hardly form a sentence. The greatest challenge for the board of NBA has been how to harmonize the salaries. Due to this various people have tried to come up with different solutions .Some argue that height ,weight and physical strength play a big role in team winning but this is not the case as some players who are short help their teams win in several occasions. To solve this problem a multiple regression analysis will be utilized to analyze the salary data. A relationship will be established between the salary and performance variables. The other challenge will be choosing the model parameters that will be significant in order to be included in the model that will be developed. This can be solved by arranging the factors affecting an NBA player salary in a decreasing order of importance...

...Question 1 For 4 Dow Jones stocks for a 15 year period, compute quarterly realized betas from daily data. Find firm specific and macroeconomic variables that help explain quarterly beta. Answer 1.1 Factors Introduction Factor model survey the sensitivity of a stock return as a function of one or more factors. There are single-factor and multi-factor models. In factors model, based on the type of factors used, it can be classified to economic and fundamental factor models. Economic factor models use macroeconomic and financial markets variables as factors, while fundamental factor models use firm-specific microeconomic variables, such as financial indicators. In recent research shows that the change in macroeconomic factors could be reflected in the change of systematic risk which impacts a stock’s expected return (Humpe & Macmillan 2007). Macroeconomic factors included industry production index, CPI, GDP, unemployment rate, inflation rate, risk premium, default premium, business cycle index and so on. From Chen (1986) notable study which uses variables include industrial production, inflation, risk premium, term structure, market index, consumption and oil prices to found out that industrial production, unanticipated change in the risk premium, unanticipated inflation, and, a slightly weaker, the unanticipated change in term structure, are the most important factors affecting expected stock returns. The 15 macroeconomic variables used as factors in our model are...

...A linear regression is worth a maximum of 5 points; a multiple regression is worth a maximum of 10 points and both are worth 13 points. You must analyze the regression(s) that you do. The better job that you do, for instance, checking the residuals and for multicollinearity, the more points you get. If you choose to do a linear regression then you must compare the list price to the square footage. You are to project out the listing price of a home that has 2750 square feet. If you choose to do the multiple regression then you must compare the list price to all the varables in the data file, square footage, number of bedroom, number of bathrooms, number of cars in the garage, and the age. You must project out the cost of a house with 2650 square feet; that is 10 years old, with 3 bed and 3 bathrooms with a garage that sleeps 3 cars.

Our proposal replaces traditional indicators (accounting ratios) with the output of a so-called multinorm analysis. The deviations of each firm from a battery of industry norms (computed by nonparametric quantile regression) are used as input variables for the classifiers. The approach is applied to predict bankruptcy of firms, and tested on a representative data set of Spanish firms.
