OMEGA priors using modes of inverse Wishart matrix

Dear NMusers, Our NONMEM User Guides are full of good advice and they are searchable. Yet when I tried to find out whether any of the estimation methods could be enticed to give me the “inverse Wishart matrix” needed to specify PRIORS for OMEGAs, I found no help. Leonid G. mentions the inverse Wishart matrix in his historic contributions to NMusers, but again I could not find out how to obtain it. If it does not happen in NONMEM, is there a tool in R that can give me that matrix? Your help is greatly appreciated, Joachim Joachim Grevel, PhD Scientific Director BAST Inc Limited BioCity Nottingham Pennyfoot Street Nottingham, NG1 1GF Tel: +44 (0)115 8120497
