TEST Subcommand (KM command)

TEST specifies the test statistic to use for testing the equality of survival distributions for the different levels of the factor.

• TEST is valid only when a factor variable is specified. If no factor variable is specified, KM issues a warning and TEST is not executed.
• If TEST is specified without a keyword, the default is LOGRANK. If a keyword is specified on TEST, only the specified test is performed.
• Each of the test statistics has a chi-square distribution with one degree of freedom.

LOGRANK. Perform the log rank (Mantel-Cox) test.

BRESLOW. Perform the Breslow (generalized Wilcoxon) test.

TARONE. Perform the Tarone-Ware test.
