TABLES Statement
The BINOMIAL option has a new LEVEL= suboption.
The BINOMIALC and RISKDIFFC options have been added to the TABLES
statement.
-
BINOMIAL < (P= value) |
(LEVEL= level-number | level-value) >
-
requests the binomial proportion for one-way tables. The BINOMIAL option
also provides the asymptotic standard error, asymptotic and exact confidence
intervals, and the asymptotic test for the binomial proportion. To request
an exact test for the binomial proportion, use the BINOMIAL option in the
EXACT statement.
To specify
the null hypothesis proportion for the test, use P=. If you omit P=value,
PROC FREQ uses 0.5 as the default for the test. By default, the
BINOMIAL option computes
the proportion of observations for the first variable level that appears in the
output. To specify a different level, use LEVEL=level-number or
LEVEL=level-value, where level-number is the variable level's
number or order in the output, and level-value is the formatted value
of the variable level.
To include a continuity correction in the asymptotic confidence interval and
test, use the BINOMIALC option instead of the BINOMIAL option.
-
BINOMIALC < (P= value) |
(LEVEL= level-number | level-value) >
-
requests the BINOMIAL option statistics for one-way tables, but includes
a continuity correction in the asymptotic confidence interval and the
asymptotic test. The BINOMIAL option statistics include the binomial
proportion, the asymptotic standard error, asymptotic and exact confidence
intervals, and the asymptotic test for the binomial proportion.
To request an exact test for the binomial proportion, use the BINOMIAL
option in the EXACT statement.
To specify
the null hypothesis proportion for the test, use P=. If you omit P=value,
PROC FREQ uses 0.5 as the default for the test. By default, the
BINOMIALC option computes
the proportion of observations for the first variable level that appears in the
output. To specify a different level, use LEVEL=level-number or
LEVEL=level-value, where level-number is the variable level's
number or order in the output, and level-value is the formatted value
of the variable level.
-
RISKDIFFC
-
requests the RISKDIFF option statistics for 2 ×2 tables,
but includes a continuity correction in the asymptotic confidence
limits. The RISKDIFF option statistics include the column 1 and
2 risks (or binomial proportions), risk differences, and their
confidence limits.
