The MVPMONITOR Procedure

TSQUARECHART Statement

TSQUARECHART < / options> ;

The TSQUARECHART statement produces a $T^2$ chart based on a principal component model that the MVPMODEL procedure computes. In a Phase I analysis, the $T^2$ statistics are computed by PROC MVPMODEL and read from the HISTORY= data set. In a Phase II analysis, the $T^2$ statistics are computed by the MVPMONITOR procedure from information about the principal component model specified in the LOADINGS= data set.

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