NAME
     desc - describing a single data distribution

SYNOPSIS
     desc [-cfhopsv] [-i interval] [-m min] [-M max] [-F|-t Ho]

DESCRIPTION
     _d_e_s_c does a number of summary statistics and frequency counts.  The
     program's input is a series of numbers separated by newlines, tabs or
     spaces.

OPTIONS
     -c   changes -f and -p options to Cumulative.

     -f   table of midpoints and Frequencies.  Data on bin boundaries end
          up in the next lower bin, except for data on the lower boundary
          of the first bin, which are put in the first bin.  Thus, the
          first bin is a doubly closed interval, while all the others are
          half open: [],(],(],(],(],...(]

     -F Ho
          requests a F-test of mean = Ho rather than 0 (also -t).

     -h   prints a Histogram with frequencies.

     -i width
          sets the Interval width for -h, -f & -p.

     -m min
          sets the Minimum of the first interval.  Numbers below it are
          ignored on input.

     -M max
          sets the Maximum value allowed.  Numbers above it are ignored on
          input.

     -o   requests Order statistics (the default with no options).

     -p   table of midpoints and Proportions.

     -s   summary Statistics according to SPSS formulas.

     -t Ho
          same as -F option, which also prints a t-test.

     -v   output statistics in Variable (name=value) format.

LIMITS
     Use the -L option to determine the program limits.  _d_e_s_c does its
     computations in either one or two passes, depending on whether the
     data is stored.  If the -i and -m options are used, then it is not
     necessary to store the data for frequency tables.  Otherwise, or if
     order statistics are requested (which require storing and sorting the
     data), then the number of input points is limited to some large
     number, which can be found with the -L option.

MISSING VALUES
     Missing data values (NA) are counted but not included in the analysis.

EXAMPLES
                        desc  -cf  -m 0  -i 10  <  file
     prints a table of Cumulative Frequencies with Minimum = 0 and Interval
     width = 10.
                       desc  -s  -m 100  -M 1000  <  file
     prints summary Statistics for inputs between 100 and 1000.
