Fig. 2.

Biplot of the factor temperature for the theoretical reaction example. The filled shapes are the scores of the level averages; the empty ones (whose spread is delimited by dashed lines) are the projections of residuals from the ASCA model. The arrows are the loadings of the product yields. The numbers in parenthesis on the axis labels express the percentage of explained variance for each PC (out of the variance explained by that specific factor).
