Changes and Enhancements to SAS/STAT Software
in V7 and V8 |

The FREQ procedure now includes a TEST statement that provides
asymptotic tests for selected measures of association and measures of
agreement. A new BINOMIAL option in the TABLES statement computes the
binomial proportion for one-way tables. You can compute the confidence
bounds of a one-way table and request the test that the proportion equals a specified
value as well as produce exact confidence bounds for the binomial
proportion and an exact *p*-value for the binomial proportion
test. You can now request that Fleiss-Cohen scores be used to compute
the weighted kappa coefficient with the AGREE(WT=FC) option. The
SCOROUT option requests that the row and column scores used for
computing statistics such as Cochran-Mantel-Haenzsel statistics and
Peason correlation be displayed.

The PCHI option in the EXACT statement computes the exact chi-square
goodness-of-fit test for one-way tables as well as the exact Pearson
chi-square test for two-way tables. The MAXTIME= option in the EXACT
statement specifies the maximum time that PROC FREQ uses to compute an
exact *p*-value.

The EXACT statement also includes the MC
option for computing Monte Carlo estimates of exact *p*-values.

The Robins, Breslow, and Greenland (1986) estimate of variance is now used to compute the confidence bounds for the odds ratio and relative risk.
