You Can Perform Out-Of-Sample Prediction by Estimating the Sample Regression

Multiple Choice

You can perform out-of-sample prediction by estimating the sample regression function for

A) all of the data,using the results to predict outcomes for all of the data,and comparing the predicted outcomes to the actual outcomes.
B) a subset of the data,using the results to predict outcomes for all of the data,and comparing the predicted outcomes to the actual outcomes.
C) all of the data,using the results to predict outcomes for a subset of the data,and comparing the predicted outcomes to the actual outcomes.
D) a subset of the data,using the results to predict outcomes for the subset not included in the regression,and comparing the predicted outcomes to the actual outcomes.
