Dear NMusers (sorry if you get this twice),
I am trying to get NONMEM to use a variable defined in $PK to be read in $MIX. Example partial code is shown below:$PKTVPROMIX=XX ; XX is not only a paramter to estimate, but is an equation $MIX
PROMIX=TVPROMIX
NSPOP=2
P(1) = PROMIX
P(2) = 1 - PROMIX
The error is as follows:AN ERROR WAS FOUND ON LINE 144 AT THE APPROXIMATE POSITION NOTED:PROMIX=TVPROMIXX THE CHARACTERS IN ERROR ARE: TVPROMIX208 UNDEFINED VARIABLE.
Whilst one would normally write everything of interest in $MIX, a problem arises when one wants to test covariates using PsN because the SCM only tests items defined in $PK/$PRED. Is there any way to have NONMEM read what is defined in $PK into $MIX?
Much thanks,
Mannie
