You discover that it takes 20 minutes to estimate each model.
You need to reduce the amount of time required to estimate each model without losing any information in the predictors.
What should you do?

  • A. Use stepControl0 to perform stepwise regression to limit the number of variables that contribute to the model.
  • B. Use selectFeatures0 to select the features that provide the most information about the outcome variable.
  • C. Use princomp0 on the correlation matrix of Features, and then use only the first 100 principle components to reduce the number of input variables.
