Re: Log-transformation

From: Leonid Gibiansky Subject:Re: [NMusers] Log-transformation Date:Mon, 31 Mar 2003 17:01:36 -0500 Daniel, You should not have any problems with negative values for log(DV). Try to start the model with the values obtained for the "not-transformed" model. Also, check whether you actually ran the control stream: your run number and output files have different names (run number is 801 but output file is 901). PDx-POP would made them equal (if check run numbers box is checked). Just to make sure: you should change not only the controls stream (Y=LOG(F)+..) but also the data file (place LOG(DV) into the DV column). Leonid
