Hi Sebastien,
It worked perfectly for me in $ERROR, but I tested it on NONMEM 7.4.3. Maybe nm
version matters.
Warm regards,
Tingjie

Thanks Tingjie for your suggestion
Unfortunately, as is, the suggested code is rejected by NONMEM 7.3 if used in
$ERROR. Some additional setup calls might be required.
An (admittedly heavy-handed) alternative that actually works is to create and
import a fortran routine (see NONMEM help topic about FUNCA, or VECTRA).
runif.f90:
FUNCTION FUNCA(X,X1,X2)
USE SIZES, ONLY: DPSIZE
REAL(KIND=DPSIZE) :: X,X1,X2,FUNCA
FUNCB = RAND()
RETURN
END
Control stream:
...
$SUBROUTINES ADVAN_ TRANS_ OTHER=runif.f90
...
$ERROR
VECTRA(1) = 0
VECTRA(2) = 0
VECTRA(3) = 0
RND = FUNCA(VECTRA)
...

Hi Sebastien,
As far as I know, you could write verbatim code to generate random numbers
during estimation. E.g:
$PK|$DES|$ERROR
RAN = any value ; initialization
"RAN = RAND(0) ; start verbatim code
A random number between 0 and 1 from uniform distribution will be assigned to
RAN. This function is called for each record of your input data. I believe it's
also possible to call it more/fewer times through checking ICALL.
Warm regards,
Tingjie

Hi,
Is it possible for NONMEM to generate a random number during an estimation run?
Thank you
Sebastien Bihorel
