PROC FREQ builds all the table requests in one pass of the data so that there is essentially no loss of efficiency. It can also be used to calculate several other metrics such as percentiles, quartiles, standard deviation, variance and sample t-test. The link attached explains the function in more detail. It is used to obtain frequency counts for one or more individual variables or to create two-way tables (cross-tabulations) from two variables. No need to export to Excel! This paper illustrates various methods ranging from using the SUM function in the simple data step to using the SUM function in SAS procedures such as PROC PRINT, PROC SUMMARY, PROC MEANS, PROC TABULATE and PROC … Watch the SAS Training Post blog for more weird tricks. Re: Sum in proc freq Posted 04-20-2012 (12460 views) | In reply to vomer I agree with Haikuo, your fully intended result is not obvious from you explaination. Each frequency table contains four columns of summary measures: The Frequency column indicates how many observations fell … (If you have a favorite method, link to it in the comment section.) The var statement indicates the variable about which statistics should be calculated; this is where the variable one is used.

PROC FREQ also displays the equivalence limits and the test-based confidence limits. PROC MEANS can be used to compute various univariate descriptive statistics for specified variables including the number of observations, mean, standard deviation, variance, minimum and maximum values, the standard error of the mean, uncorrected sum of squares, corrected sum of squares, the

If you omit the TABLES statement, PROC FREQ generates one-way frequency tables for all data set variables that are not listed in the other statements.

I've previously shown how to use PROC FORMAT in SAS to bin numerical variables and give each group a meaningful name such as 'Low,' 'Medium,' and 'High.' *PROC SUMMARY EXAMPLES; * This creates an alias for the directory; libname class "c:\data\class\fw893"; PROC IMPORT OUT= class.FISH DATAFILE= "C:\Data\class\FW893\Fish_data.xls" DBMS=EXCEL2000 REPLACE; GETNAMES=YES; RUN; *This prints out data in the "active" table; proc print; run; *=====; * This section produces summary statistics for each species across all samples; proc … University of Rochester Medical Center . PROC FREQ in SAS is a procedure for analyzing the count of data.

PROC FREQ displays two one-sided tests (TOST) for equivalence, which include test statistics (Z) and probability values for the Lower and Upper tests, together with the Overall probability value. PROC FREQ builds all the table requests in one pass of the data so that there is essentially no loss of efficiency. For example - if we need the frequency of each model for each make in each car type category, then we need to use the TABLES option of PROC FREQ. This Beginning Tutorial has just scratched the surface of the functionality of PROC FREQ.
