Base SAS 9.4 Procedures Guide : Statistical Procedures, Fifth Edition

Provides complete documentation of the Base SAS statistical procedures (CORR, FREQ, and UNIVARIATE), including introductory examples, syntax, computational details, and advanced examples.

The fourth maintenance release of Base SAS 9.4 includes enhancements to the FREQ and UNIVARIATE statistical procedures.

FREQ Procedure Enhancements:

The new AGREE(PABAK) and AGREE(AC1) options produce the prevalence-adjusted bias-adjusted kappa coefficient and Gwet’s AC1 agreement coefficient, respectively. The AGREE(KAPPADETAILS) option provides the following statistics: observed agreement and chance-expected agreement components of the simple kappa coefficient, maximum possible kappa, prevalence index, and bias index. The AGREE(WTKAPDETAILS) option provides the observed agreement and chance-expected agreement components of the weighted kappa coefficient.

You can now specify nonzero null values for the simple and weighted kappa tests by using the AGREE(NULLKAPPA=) and AGREE(NULLWTKAP=) options. You can specify the degrees of freedom for Bowker’s test of symmetry by using the AGREE(DFSYM=) option.

When you specify any of the AGREE options that are new in SAS 9.4M4, PROC FREQ displays all tables of AGREE statistics in tabular format (instead of factoid format); to display preexisting tables in their original factoid format, you can specify the AGREE(TABLES=RESTORE) option.
