Dear all, I am looking for a R package or R code dealing with multivariate type II regressions. I know the "lmodel2" and "smatr" packages, but they just allow to perform bivariate type II regressions. Ideally, I would use the method described by McArdle (1988) called "standard minor axis" regression, and use the bootstrap to calculate confidence intervals for each coefficient. I would appreciate any help you could provide. Thank you in advance, Angélique McArdle (1988). The structural relationship: regression in biology. Can. J.
