Essentially regression analysis is what this course is all about.

When we do regression analysis, we

I. determine how to specify the model

II. decide which explanatory variables to include in the model

III. estimate the parameters of the model using the data

IV. use the model to predict the response given the values of the explanatory variables

V. assess the usefulness of the model in explaining the variability in the response variable

Group of answer choices

a. I, II and III only

b. I only

c. I, II, III, IV and V

d. I and II only

Answer #1

The answer is:

All the above hold true for regression analysis:

I. determine how to specify the model

II. decide which explanatory variables to include in the model

III. estimate the parameters of the model using the data

IV. use the model to predict the response given the values of the explanatory variables

V. assess the usefulness of the model in explaining the variability in the response variable

All 5 list the purpose of the regression analysis including specification, prediction, and usefulness of the model.

Discuss all of the assumptions Briefly what problem when they are not met How to solve it The seven classical assumptions are: I. The regression model is linear, is correctly specified, and has an additive error term II. The error term has a zero population mean III. All explanatory variables are uncorrelated with the error term IV. Observations of the error term are uncorrelated with each other (no serial correlation) V. The error term has a constant variance (no heteroskedasticity)...
