23 gru 2021 · In this article, we discuss how to format variables in the most used SAS procedures, namely PROC MEANS, PROC FREQ, and PROC TABULATE. Generally speaking, you use the FORMAT statement to format a variable in SAS procedures.
The PROC FREQ procedure is used to summarize categorical variables in SAS. It calculates count/frequency and cumulative frequency of categories of a categorical variable. It can also produce bar charts and tests for association between two categorical variables.
The PROC FREQ statement invokes the procedure and optionally identifies the input data set. By default, the procedure uses the most recently created SAS data set. Table 3.4 lists the options available in the PROC FREQ statement. Descriptions follow in alphabetical order.
Examples: FREQ Procedure. Subsections: 3.1 Output Data Set of Frequencies. 3.2 Frequency Dot Plots. 3.3 Chi-Square Goodness-of-Fit Tests. 3.4 Binomial Proportions. 3.5 Analysis of a 2x2 Contingency Table. 3.6 Output Data Set of Chi-Square Statistics. 3.7 Cochran-Mantel-Haenszel Statistics.

PROC FREQ uses 3 of the 20 formatting characters that SAS provides. You can specify three characters in formchar-string to draw the vertical separators (1), the horizontal separators (2), and the vertical-horizontal intersections (7) in crosstabulation tables.
