**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

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