A business built a simple linear regression model from a sample of 20 units. The resulting linear model equation is y' = 7.53 + 0.225x.

The correlation coefficient is 0.55. What is the value of the t critical value used to make the rejection region for the test "Is the correlation coefficient significantly different from zero?" α= 0.01

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.

Discuss the underlying assumptions of a simple linear regression model; multiple regression model; and polynomial regression.

In a simple linear regression model, the ANOVA F test is a test of model significance (i.e. a test of whether the linear regression model is significantly better than the trivial model yi = β0 + εi). This test can be performed in another way (i.e. by the 'extra sum of squares' or ESS method considering the simple linear regression model as the 'full model' and the trivial model yi = β0 + εi as the 'reduced model'). There is...
