    SN-005120 ***Alert Note***

    Incorrect standard errors and parameter tests possible with NOPRINT and
    LACKFIT options

    Product: SAS/STAT
    Component: PROBIT procedure
    Priority: ALERT

      If you specify the NOPRINT and LACKFIT options in the PROC PROBIT
      statement and if the Pearson chi-square statistic is significant at the
      level specified in the HPROB= option (0.10 by default), then the
      covariance matrix should be multiplied by the heterogeneity factor, but
      is not.

      To circumvent this problem, remove the NOPRINT option and use:


      to suppress the procedure output.
