RE: st: perceptual maps in Stata

[jverkuilen <jverkuilen@gc.cuny.edu>]

###Does anyone know of some Stata code to do a perceptual map (MDPREF or 
PREFMAP)?###

Those are SVD-based procedures if I recall right (it's been a while since Larry Hubert's multivariate course). Proper choice of the normalization in -biplot- shold do what you want.
