gbstat(1) 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.


add the sample median to the estimated statistics
print statistics for each column of input
short: mean std skew kurt adev min max (median) num
select output: mean,std,skew,kurt,adev,min,max,median,num,mode
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.
