The UNIVARIATE Procedure
Summarizing a Data Distribution
Figure 1 shows a table of basic summary measures and a table of extreme observations for the loan-to-value ratios of 5,840 home mortgages. The ratios are saved as values of the variable LoanToValueRatio in a data set named HomeLoans. The following statements request a univariate analysis:
ods select BasicMeasures ExtremeObs;
proc univariate data=HomeLoans;
var LoanToValueRatio;
run;
The ODS SELECT statement restricts the default output to the tables for basic statistical measures and extreme observations.
