PCTL Function

Arguments

n

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

Default:

definition 5

percentage

is a numeric constant, variable, or expression that specifies the percentile to be computed.

Requirement:

is numeric where, 0 percentage 100.

value

is a numeric variable, constant, or expression.

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 formula that used in PROC UNIVARIATE. For more information, see SAS Elementary Statistics Procedures in Base SAS Procedures Guide.
