Question:
The following analyses are based on a dataset with 4 variables, Y, X1,X2 and X3.Note C(P) is a measure of bias in a model (and bias is bad...)The expected value of C(P) is the value of p for a given model.The more C(P) differs from p the more biased the model is.
Model | R2 | C(P) | |||||
Y=X1 | .39 | 6.2 | |||||
Y=X2 | .10 | 2.1 | |||||
Y=X3 | .29 | 5.7 | |||||
Y=X1 | .49 | 3.1 | |||||
Y=X2 X3 | .39 | 2.2 | |||||
Y=X1 | .58 | 6.1 | |||||
Y=X1 X2 X3 | .68 | 4.0 |
