Yaning,
Sorry for the confusion. I wrote the reply in some haste because of pre-Christmas
pressures and got the predictive formula for C(T) wrong.
One solution is to add C from the previous record as a data item (CPRE) and TIME as
TPRE:
ID TIME TPRE C CPRE SLOP DV
1 1 1 0 0 0 10 ; first record for this subject
1 2 1 1 0 1 8
1 3 2 3 1 2 4
then compute C(T) in $DES:
$DES
CNOW=CPRE+SLOP*(T-TPRE)
