MEANING: NONMEM-PRED common
CONTEXT: PRED routine
USAGE:
COMMON /NMPRD8/ I_REC
INTEGER I_REC
DISCUSSION:
A PRED routine may be recursive, i.e., for single-subject data, with a
given data record, the PRED computation depends on the values of vari-
ables that PRED computes with any of the previous records. PREDPP is
---
such a routine.
By default, PRED is taken to be nonrecursive. At ICALL=0 or 1, PRED
can declare itself to be recursive, by including the variable I_REC in
NONMEM-PRED common NMPRD8 and setting it to 1.
The setting of I_REC can be changed from problem to problem, but
regardless of the setting, with a given problem the setting is always
taken to be 0 if the data for that problem are population data.
If I_REC is set to 1 and the repetition feature is not used, the SPE-
CIAL option need not appear on the $COVARIANCE record; the special
computation is automatically used.
PREDPP sets I_REC to 1 at ICALL=1.
I_REC can be set explicitly in abbreviated code. With recursive $PRED
abbreviated code and with single-subject data, if I_REC is not set to
a value in $PRED, then NM-TRAN causes I_REC to be set to 1.
