The FREQ Procedure

• produces one-way to n-way frequency and contingency (crosstabulation) tables
• computes tests and measures of association for two-way tables
• provides stratified analysis for n-way tables by computing statistics across, as well as within, strata
• computes goodness-of-fit tests for equal proportions or specified null proportions for one-way frequency tables
• provides confidence limits and tests for binomial proportions, including tests for noninferiority and equivalence for one-way frequency tables
• compute various statistics to examine the relationships between two classification variables. The statistics for contingency tables include the following:
  • chi-square tests and measures
  • measures of association
  • risks (binomial proportions) and risk differences for 2 x 2 tables
  • odds ratios and relative risks for 2 x 2 tables
  • tests for trend
  • tests and measures of agreement
  • Cochran-Mantel-Haenszel statistics
• computes asymptotic standard errors, confidence intervals, and tests for measures of association and measures of agreement
• Exact p-values and confidence intervals are available for many test statistics and measures
• obtain separate analyses on observations in groups
• use either raw data or cell count data to produce frequency and crosstabulation tables
• creates a SAS data set that contains the computed statistics
• uses ODS to create a SAS data set corresponding to any table
• supports ODS Graphics
