The SCORECHART statement produces univariate control charts of principal component scores. In a Phase I analysis, the scores are computed by PROC MVPMODEL and read from a HISTORY= data set. In a Phase II analysis, PROC MVPMONITOR computes the scores from process data contained in a DATA= data set and information about the principal component model that is specified in the LOADINGS= data set.
Table 13.1 summarizes the options available in the SCORECHART statement.
