¥Explain the dark/light red/blue shading
¥Compared to the PCs
–Rotation (using varimax) gives separate regions in the
first 2 PCs, rather than overall temperature and a contrast between regions
–SCoTLASS gives a simpler version of the rotated PCs
–SCoT (a technique that maximises a criterion combining variance and simplicity) gives a simpler
version of the unrotated
PCs; so do simple components,
but simplicity in a different
sense
