# gbstat(1)

Basic descriptive statistics of data

## 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,var, 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.
