To specify how the model parameters are to be estimated, select Method under Fit in the left pane of the model window. For more information about available methods of parameters estimation, see Chapter 18, "The MODEL Procedure," (SAS/ETS User’s Guide).

Figure 47.34 Model Fit Method

This right pane has the following controls and fields:

Estimation Methods check boxes

enable you to select the corresponding estimation method. The check boxes correspond to the methods implemented in PROC MODEL, all of which aim to minimize an objective function.

Divisor of Variance

specifies a degrees-of-freedom correction in estimating the variance matrix. This could be the sum of the weights or the sum of the weights minus the model degrees of freedom.
