Syntax: APPROXIMATE numberwhere number is a non-negative integer which is less than or equal to
MAXITS.
This first derivative based approximation is more robust than the matrix of

second derivatives when the parameter estimates are a long way from their
maximum likelihood solutions. For this reason, the first
Note that, even if convergence is achieved within the first The default number of approximate iterations is 5. The current setting of the APPROXIMATE parameter may be obtained by issuing the DISPLAY SETTINGS command. The APPROXIMATE command has no effect on model fitting instigated using the LFIT command. |
