Sorry for triple-posting : I seem to have a problem w/ my mail client. Hi,
Is there a way, documented or not, to extract the intercept term (the alpha_0 the MASS book) from a ppr() (Projection Persuit Regression) fit? Thanks, Vadim ## Example: n <- 1000 data <- data.frame(x= rnorm (n), y= rnorm (n)) a <- 10 data$z <- evalq(a + atan (x + y) + rnorm (n), data) data.ppr <- ppr(z ~ x + y, data=data, nterms =1) ## how to extract a = 10 from data.ppr?
