PCTL Function

Computes percentiles

Category: Descriptive Statistics

Syntax

PCTL < n >( percentage , value1 <, value2, >)

Arguments

n

• is a digit from 1 to 5 which specifies the definition of the percentile to be computed.

• Default: definition 5

percentage

• specifies the percentile to be computed.

• Requirement: is numeric where, 0 ‰ percentage ‰ 100.

value

• is numeric.

Details

The PCTL function returns the percentile of the nonmissing values corresponding to the percentage. If percentage is missing, less than zero, or greater than 100, the PCTL function generates an error message.

Note: The formula that is used in the PCTL function is the same as the function that is used in PROC UNIVARIATE. For more information, see 'SAS Elementary Statistics Procedures' in Base SAS Procedures Guide .
