Dear list, one year before I installed the add-on package lqs to perform robust estimation of multivariate location and scatter (cov.mve, cov.mcd, cov.rob). I had the feeling that there was something wrong with the results (perhaps I can reproduce it if necessary). Now I looked in the CRAN-archive to see if there is a new version of lqs or if cov.rob had been included in the base package in the meantime. I browsed through the recent help.start()-manual and found the help pages for the robust cov-functions, but it is indicated that they still belong to the package lqs. But a package lqs is no longer offered. Is the package discarded (perhaps because of errors), or am I simply too confused to search at the right place? The most improtant question is of course: How to perform minimum covariance determinant/minimum volume ellipsoid estimation with R?

Use library(lqs) to access it. If there are bugs in it, we''d appreciate a report with a demonstration.... -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /''_ --- Dept. of Biostatistics 2200 Cph.
