NMusers] Error model

From: tgordi@buffalo.edu Subject:NMusers] Error model Date:Thu, 10 Apr 2003 21:10:32 -0400 Dear all, I am trying to write an error model for a system, where 2 different measurements were made. One of these is log-transformed while the other is not. I would like to test an additive model for the log- transformed data and a proportiona error model for the other measurement. The two measurements are marked by a value of 1 or 0 in a separate column called PKone, where 1 means the first measurement and 0 means the second. I have tried to combine the two models in a couple of different ways but have not been successful. Any suggestions or references that I can look up? Toufigh Gordi
