    SAS Note: SN-003202
    Product: STAT
    Component: TTEST

    Title:
    PROC TTEST incorrectly computes many weighted statistics

    Keywords:
    TTEST WEIGHT STANDARD DEVIATION CL UPPER LOWER INCORRSTAT STATISTICS
    INCORROUT ERROR

    PROC TTEST incorrectly computes the standard deviation, upper and
    lower confidence limits for the standard deviation, upper and lower
    confidence limits for the mean, standard error, t-statistic and p-value
    of the t-statistic when there is a WEIGHT statement.

    PROC MEANS, PROC GLM or PROC MIXED can be used to correctly calculate
    these weighted statistics.
