The ROBUSTREG Procedure

TEST Statement

  • <label:> TEST effects;

When you use M estimation and MM estimation, the TEST statement provides a means of obtaining a test for the canonical linear hypothesis about the parameters of the tested effects

\[  \theta _{j} = 0, \  \  j=i_1,\ldots ,i_ q  \]

where q is the total number of parameters of the tested effects.

PROC ROBUSTREG provides two kinds of robust tests: the $\rho $ test and the $R_ n^2$ test. They are described in the section Details: ROBUSTREG Procedure. No test is available for LTS and S estimation.

The optional label, which must be a valid SAS name, is used to label output from the corresponding TEST statement.
