The MVPMONITOR Procedure

The OUTHISTORY= data set contains all the variables in the input data set plus new variables that contain the principal component scores, residuals, and other computed values listed in Table 13.7.

The names of the score variables are formed by concatenating the value given by the PREFIX= option (or the default Prin, if PREFIX= is not specified) and the numbers 1, 2, …, j, where j is the number of principal components in the model.

The names of the residual variables are formed by concatenating the value given by the RPREFIX= option (or the default R_, if RPREFIX= is not specified) and the names of the process variables used in the analysis. Residual variables are created only when the number of principal components in the model is less than the number of process measurement variables in the input data set.

You can save multivariate control chart statistics, control limits, and related information by specifying the OUTTABLE= option in an SPECHART or TSQUARECHART statement. An OUTTABLE= data set contains the variables listed in Table 13.8.
