SN-000852 *** ALERT NOTE *** PRODUCT: STAT

TITLE: Results are incorrect when LOGORVAR() option is specified

KEYS: INCORRSTAT LOGORVAR GEE REPEATED ALR ALTERNATING LOGISTIC REGRESSION
       ZDATA= ZROW= YPAIR=

    If the LOGORVAR() option is specified on the REPEATED statement in PROC
    GENMOD, the design matrix for the log odds ratio is incorrectly
    constructed, resulting in incorrect results. You can avoid the problem
    by directly specifying the design matrix via the LOGOR=ZFULL, ZDATA=,
    ZROW=, and YPAIR= options on the REPEATED statement.
