Purpose
Indicates that the estimated number of cases is to be computed for each record after a model is fit. The NOFV command is used to remove the %FV variable and end the automatic computation of fitted values.
Programs
AMFIT, GMBO
Syntax
FV
NOFV
Remarks
The FV command defines a variable called %FV which is used to store the estimated number of cases. The values of this variable are recomputed after each model is fit. In AMFIT, the estimated number of cases is computed as the product of the number of person-years and the estimated rate for each record. In GMBO, the estimate is the product of the number of trials and the estimated response probability.
If the FV command is given then the default estimates of the background (stored in %BK) and excess (stored in %EX) cases are computed.
