PRESS statistic from a regression using a power transformation

This macro computes the model fits, residuals, deleted fits, deleted prediction sum of squares ((PRESS) residuals, and the PRESS statistic in the original units of the response when a power transformation of the response is applied in a linear regression.

Required Inputs

  • The number of predictors in the regression
  • The storage columns for the predictors
  • The storage column for the response
  • The power transformation parameters

Running the Macro

Suppose you have one predictor variable stored in C1, and the response variable is in C2. The transformation parameter value was -1.

  1. Click anywhere in the Session window and choose Editor > Show Command Line.
  2. At the command prompt (MTB>), type the following:
  3. Press Enter. You will be prompted for additional information. For example:
    Please enter the number of predictor variables in the regression...
    DATA> 1
    Please enter column number of predictor variable...
    DATA> 1
    Please enter column number of response variable...
    DATA> 2
    Please enter response power transformation parameter value...
    DATA> -1 <-- reciprocal transformation of response specified
