Options

    generate(newvar) specifies the name of the new variable.  It is a required option.

    p(#) specifies the fraction of the observations to be modified in each tail. p should be greater
        than 0 and less than 0.5 and imply a value of h as just below.

    h(#) specifies the number of the observations to be modified in each tail. h should be at least 1
        and less than half the number of non-missing observations.

    Just one of p() and h() should be specified.

    highonly and lowonly specify that Winsorizing should be one-sided, referring only to the tail with
        the highest values or only to the tail with the lowest values, respectively. These options
        should not be specified together.
