gbstat - Basic descriptive statistics of data

**gbstat** [*options*]

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.

**-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

- 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.
