In: Statistics and Probability
Data are collected on 15 individuals and two models are considered:
Model 1: model with 2 predictors (A and B), SStotal = 360, SST = 200
Model 2: model with 4 predictors (A, B, C and D), SStotal = 360, SST = 270
1. The standard error of the complete model is equal to _______
2. The number of predictors to test to evaluate whether the restricted model is sufficient is equal to _______
3. The partial F-test in 2. is equal to _______
4. The critical value (rejection region) for the partial F-test is equal to _______
5. The adjusted coefficient of determination for the complete model is equal to ______ %
