Measures of relative dispersion                                 [sg31: STB-23]
-------------------------------

        ^rspread^ varlist [^if^ exp] [^in^ exp] [^,^ ^gr^aph ]

produces several measures of relative dispersion or spread or inequality for
each variable in the varlist.  If the ^graph^ option is specified a Lorenz
curve will also be produced.  The Lorenz curve is automatically saved in
^lorenz#.gph^,  where # is the order of the variable in the varlist.  There is
a limit of 99 graphs at any one time, and, if there is already a graph with
this name, it is replaced.

^rspread^ displays the following statistics:

    mean deviation about the mean (MD)
    mean deviation about the median (AD)
    mean difference (MeanDif)
    Coefficient of Variation (CV)
    Coefficient of Dispersion (CD)
    GINI coefficient
    Standard Error(MEAN)
    Max. Percentage Deviation from Average
