Multiple Linear Regression Model. We consider the problem of regression when the study variable depends on more than one explanatory or independent variables, called a multiple linear regression model. This model generalizes the simple linear regression in two ways. ... So first, we discuss the test of a general linear hypothesis. Test of ...

In the case of simple linear regression we saw that the above hypothesis test was equivalent to the hypothesis test: with . In the case of multiple regression, the above hypothesis test is equivalent to the following hypothesis test: with alternative hypothesis. At least one coefficient is not equal to zero.

The F-test in multiple regression tests a different hypothesis than in simple linear regression. It is important to note that the alternative hypothesis is that at least one of the explanatory variables is a significant predictor of the response variable.

An application of the multiple regression model generated the following results involving the F test of the overall regression model: p-value = 0.0012, R2 = 0.67, s = 0.076. The null hypothesis, which states that none of the explanatory variables are significantly related to the response variable, should be rejected, at the 0.05 level of ...

F-test of the Model in Multiple Linear Regression. This generalizes to give an F-test of a multiple linear regression. We test the "Base" modelagainst the "Full" model . The hypotheses are:, i.e., all slopes equal zero. Thus none of the are linearly related to. at least one of theis not zero, i.e., some of …

Fit a multiple linear regression model to these data. Perform a residuals analysis using graphical methods discussed in class (you do not have to plot a normal curve on the histogram of your residuals). Test for the significance of the regression at α = 0.05. Use the t-test to assess the contribution of each regressor to the model.
