Sas Proc Means Standard Error

an output data set. When you use a BY statement, each observation in the OUT= data set corresponds to one of the BY groups. Otherwise, the OUT= data set proc means sum by group contains only one observation. You can use any number of OUTPUT statements proc means percentile in the UNIVARIATE procedure. Each OUTPUT statement creates a new data set containing the statistics specified in that statement. proc means class You must use the VAR statement with the OUTPUT statement. The OUTPUT statement must contain a specification of the form keyword=names or the PCTLPTS= and PCTLPRE= specifications. See Example 4.7

and Example 4.8. OUT=SAS-data-set identifies the output data set. If SAS-data-set does not exist, PROC UNIVARIATE creates it. If you omit OUT=, the data set is named DATAn, where n is the smallest integer that makes the name unique. keyword=names specifies the statistics to include in the output data set and gives names to the new variables that contain the statistics. Specify proc means ucla a keyword for each desired statistic, followed by an equal sign, followed by the names of the variables to contain the statistic. In the output data set, the first variable listed after a keyword in the OUTPUT statement contains the statistic for the first variable listed in the VAR statement, the second variable contains the statistic for the second variable in the VAR statement, and so on. If the list of names following the equal sign is shorter than the list of variables in the VAR statement, the procedure uses the names in the order in which the variables are listed in the VAR statement. The available keywords are listed in the following tables: Table 4.43 Descriptive Statistic Keywords Keyword Description CSS corrected sum of squares CV coefficient of variation KURTOSIS kurtosis MAX largest value MEAN sample mean MIN smallest value MODE most frequent value N sample size NMISS number of missing values NOBS number of observations RANGE range SKEWNESS skewness STD standard deviation STDMEAN standard error of the mean SUM sum of the observations SUMWGT sum of the weights USS uncorrected sum of
