PROC GLMSELECT was used for building a model predicting the natural log of a baseball player's salary from certain performance and longevity statistics. The model used backward elimination using SBC as its selection criterion. The sequence of steps is summarized in the graphic shown below:

At Step 9 number of at bats (nAtBat) was removed from the model. Why was it removed?

  1. Removing nAtBat had the largest effect on the parameter estimate of nHits.
  2. The p-Value for nAtBat was largest.
  3. Removing nAtBat yielded the largest improvement to SB
  4. The p-Value for nAtBat was smallest.

Answer(s): B



Refer to the exhibit.
