Multiple Regression Analysis 16 3. Multiple Regression Analysis The concepts and principles developed in dealing with simple linear regression (i.e. one explanatory variable) may be extended to deal with several explanatory variables. We begin with an example of two explanatory variables‚ both of which are continuous. The regression equation in such a case becomes: Y = α + β1x1 + β2 x2 It is customary to replace α with β 0‚ and so all future regression equations would be written as

your Part II Final Project assignment. When constructing a multiple regression model‚ we must ask the question “Does a linear relationship exist between the dependent variable and the independent variables. Based on the multiple regression model of the Virginia hospitals data‚ all of the independent variables are not significant predictors of the dependent variable. This is evidenced by the varying p-values shown in the regression analysis. The null hypothesis for each independent variable states
