The result of the test is returned in the macro variable &LOGTEST. The value of the &LOGTEST variable is "LOG" if the model fit to the log transformed data has a larger log likelihood than the model fit to the untransformed series. The value of the &LOGTEST variable is "NONE" if the model fit to the untransformed data has a larger log likelihood. The variable &LOGTEST is set to "ERROR" if the %LOGTEST macro is unable to compute the test due to errors. Results are printed when the PRINT=YES option is specified. Results are stored in SAS data sets when the OUT= option is specified.
