Answer to Question 1

Once a model has been constructed, it can be used to learn details of the system and process being studied. In regression analysis, this may involve finding confidence intervals for the model parameters, testing hypotheses of interest, or forecasting future values of the dependent variable, given assumed values of the independent variables. It is important to recognize that inference of this sort is based on the assumption of an appropriate model specification and estimation. In general, the more severe are any specification or estimation errors, the less reliable is any inference derived from the estimated model.

Answer to Question 2

FALSE
