What’s New in SAS/STAT 14.1

MI Procedure

The NIMPUTE= option supports the PCTMISSING suboption for specifying the number of imputations as the percentage of incomplete cases. The new default is NIMPUTE=25.

The new LIKELIHOOD=AUGMENT suboption of the LOGISTIC option in the FCS and MONOTONE statements adds observations to the likelihood function in the computation of maximum likelihood parameter estimates for logistic regression. This suboption is applicable in situations where the likelihood estimates do not otherwise exist because the data points exhibit a complete separation pattern or a quasi-complete separation pattern. The method of augmenting the data is from White, Daniel, and Royston (2010).
