DESC(1)

NAME
desc - describing a single data distribution

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

DESCRIPTION
desc 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. desc 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.
