When cоmpаring twо mоdels using Akаike's Informаtion Criterion (AIC) and the Bayesian Information Criterion (BIC), we favor the model with the lowest values of AIC and BIC.
Answer the fоllоwing questiоns in the text box below showing cаlculаtions аnd/or brief justification. [6 points] Calculate the three missing values in this Anova table for the multiple linear regression model, E(Y) = β0 + β1X1 + β2X2 + β3X3 + β4X4 + β5X5 + β6X6 + β7X7 + β8X8. Source of variation DF SS Regression ? 109.18 Residual error ? ? Total 38 150 Regression DF = Residual error DF = Residual error SS = [8 points] Sequential sums of squares for the model in part (a) were as follows: Source of variation DF SS X1 1 0.10 X2 1 40.00 X3 1 1.00 X4 1 55.00 X5 1 2.50 X6 1 0.08 X7 1 6.50 X8 1 4.00 Use information in this table and the table in part (a) to perform a hypothesis test at significance level 0.05 to determine whether predictors X5, X6, X7, and X8 are significantly linearly related to Y upon controlling for the remaining predictors X1-X4 using a partial F test. Write the null and alternative hypotheses, the value of the test statistic (show calculations clearly), the decision rule, and the conclusion. [Use the fact that the 95th percentile of an F-distribution with 4 numerator DF and 30 denominator DF is 2.69]. [6 points] Later it was decided to consider a regression of Y on the first 4 predictors only. Use information from both tables to calculate adjusted R2 for the model with only the first 4 predictors. Clearly show your work. [2 points] Given only the information in both tables, is it possible to test whether X1 and X3 can be dropped from the 4-predictor model? Give a brief argument supporting your answer. [You do not have to do a test, even if one is possible.]
