TEST Subcommand (CSCOXREG command)

The TEST subcommand specifies the type of test statistic and the method of adjusting the significance level to be used for hypothesis tests requested on the MODEL, CUSTOM, and PRINT subcommands.

TYPE Keyword

The TYPE keyword indicates the type of test statistic.

F. Wald F test. This is the default test statistic if the TYPE keyword is not specified.

ADJF. Adjusted Wald F test.

CHISQUARE. Wald chi-square test.

ADJCHISQUARE. Adjusted Wald chi-square test.

PADJUST Keyword

The PADJUST keyword indicates the method of adjusting the significance level.

LSD. Least significant difference. This method does not control the overall probability of rejecting the hypotheses that some linear contrasts are different from the null hypothesis values. This is the default.

BONFERRONI. Bonferroni. This method adjusts the observed significance level for the fact that multiple contrasts are being tested.

SEQBONFERRONI. Sequential Bonferroni. This is a sequentially step-down rejective Bonferroni procedure that is much less conservative in terms of rejecting individual hypotheses but maintains the same overall significance level.

SIDAK. Sidak. This method provides tighter bounds than the Bonferroni approach.

SEQSIDAK. Sequential Sidak. This is a sequentially step-down rejective Sidak procedure that is much less conservative in terms of rejecting individual hypotheses but maintains the same overall significance level.
