Probability Functions

You can call the following Base SAS functions for computing probabilities that are associated with statistical distributions. The functions that are indicated with an asterisk (*) are deprecated. You should use the CDF function instead.

CDF

computes cumulative distribution functions

LOGCDF

returns the logarithm of a left cumulative distribution function

LOGPDF

computes the logarithm of a probability function

LOGSDF

computes the logarithm of a survival function

PDF

computes probability density functions

POISSON*

returns the probability from a Poisson distribution

PROBBETA*

returns the probability from a beta distribution

PROBBNML*

returns the probability from a binomial distribution

PROBBNRM

returns the probability from the bivariate normal distribution

PROBCHI*

returns the probability from a chi-squared distribution

PROBF*

returns the probability from an F distribution

PROBGAM*

returns the probability from a gamma distribution

PROBHYPR*

returns the probability from a hypergeometric distribution

PROBMC

returns a probability or a quantile from various distributions for multiple comparisons of means

PROBNEGB*

returns the probability from a negative binomial distribution

PROBNORM*

returns the probability from the standard normal distribution

PROBT*

returns the probability from a $t$ distribution

SDF

computes a survival function
