NAME

       gbstat - Basic descriptive statistics of data

SYNOPSIS

       gbstat [options]

DESCRIPTION

       Sample  statistics.  Compute  mean,  standard  deviation, skewness, kurtosis, average deviation, minimum,
       maximum, median (if option -m is specified) and number of valid observations. Option  -O  allows  one  to
       select  specific  statistics. With option -t statistics are printed for each column of data separately. A
       header line is added with the meaning  of  the  different  columns.   The  mode  is  computed  using  the
       Half-Sample method.

OPTIONS

       -m     add the sample median to the estimated statistics

       -t     print statistics for each column of input

       -s     short: mean std skew kurt adev min max (median) num

       -O     select output: mean,std,skew,kurt,adev,min,max,median,num,mode

       -o     set the output format (default '%12.6e')

       -F     specify the input fields separators (default " \t")

       -h this help

EXAMPLES

       gbstat -O median,kurt < file
              compute the median and the kurtosis of all the data in 'file'

       gbstat -ts < file
              compute  statistics  for  each  columns  separately.   Since  option -s is provided, the header is
              omitted.
