SIMPLE VERSUS MULTIPLE REGRESSION The difference between simple and multiple regression is similar to the difference between one way and factorial ANOVA. Like one-way ANOVA‚ simple regression analysis involves a single independent‚ or predictor variable and a single dependent‚ or outcome variable. This is the same number of variables used in a simple correlation analysis. The difference between a Pearson correlation coefficient and a simple regression analysis is that whereas the correlation does

Marlene A. Smith & Peter G. Bryant) The most important factor in determining the selling prices ofhouses is to know the features that drive the selling prices of the house. People tend to have more interest in houses with multiple bed rooms/bathrooms‚ fireplace‚ garage for multiple cars and location while choosing a house. So‚ a house that meets this requirement tends to be priced more and the house with these features being absent is priced low. According to the survey conducted by Marlene A. Smith

CWRU Regression Project Report OPRE 433 Tianao Zhang 12/5/2011 Introduction According to the data I’ve received‚ there are 6578 observations. The data base is composed by 13 columns and 506 rows. All the explanatory variables are continuous as well as the dependent variable and there are no categorical variables. My goal is to build a regression model to predict the average of Y or particular Y by a given X. 1. Do the regression assumptions such as Constant Variance‚ Normality and Independence

Introduction: The main idea of a multiple regression analysis is to understand the relationship between several independent variables and a single dependent variable. (Lind‚ 2004) A model of the relationship is hypothesized‚ and estimates of the parameter values are used to develop an estimated regression equation.(abyss.uoregon.edu) The multiple regression equation used to describe the relationship is: Y’ = a + b1X1 + b2X2 + b3X3 + . + bkXk. It is used to estimate Y given selected X values

Multiple Regression Project The is the only deliverable in Week Four. It is the case study titled “Locating New Pam and Susan’s Stores‚” described at the end of Chapter 12 of your textbook. The case involves the decision to locate a new store at one of two candidate sites. The decision will be based on estimates of sales potential‚ and for this purpose‚ you will need to develop a multiple regression model to predict sales. Specific case questions are given in the textbook‚ and the necessary data
