From:VPIOTROV@PRDBE.jnj.com Subject:RE: [NMusers] large CV Date:Thu, 6 Mar 2003 11:20:59 +0100 When selecting ETAs to be excluded, I would not recommend to rely on omega estimates. This way you could exclude a random effect, which would be essential. Better way (although not ideal, too) is to run sequentially a series of reduced models with each ETA excluded one at a time and then compare MOF values. ETAs associated with an insignificant increase of MOF can be safely excluded. Best regards, Vladimir _______________________________________________________
