The MVPMONITOR Procedure

SPECHART Statement

SPECHART < / options>;

The SPECHART statement produces a control chart of the squared prediction error (SPE) statistics based on a principal component model that the MVPMODEL procedure computes. In a Phase I analysis, the SPE statistics are computed by PROC MVPMODEL and read from the HISTORY= data set. In a Phase II analysis, the SPE statistics are computed by the MVPMONITOR procedure from information about the principal component model that is specified in the LOADINGS= data set.

Table 13.2 summarizes the options available in the SPECHART statement. For detailed descriptions, see the section Common Chart Statement Options.
