PROGRAM:
NAME
pkstatascii - program to calculate basic statistics from text file
SYNOPSIS
pkstatascii -i input [-c column] [options] [advanced options]
DESCRIPTION
pkstatascii calculates basic statistics of a data series in a text file.
OPTIONS
-i filename, --input filename
name of the input text file
-size, --size
sample size
-rnd number, --rnd number
generate random numbers
-dist function, --dist function
distribution for generating random numbers, see
http://www.gn/software/gsl/manual/gsl-ref_toc.html#TOC320 (only uniform and
Gaussian supported yet)
-rnda value, --rnda value
first parameter for random distribution (mean value in case of Gaussian)
-rndb value, --rndb value
second parameter for random distribution (standard deviation in case of Gaussian)
-mean, --mean
calculate mean
-median, --median
calculate median
-var, --var
calculate variance
-stdev, --stdev
calculate standard deviation
-skew, --skewness
calculate skewness
-kurt, --kurtosis
calculate kurtosis
-sum, --sum
calculate sum of column
-mm, --minmax
calculate minimum and maximum value
-min, --min
calculate minimum value
-max, --max
calculate maximum value
-hist, --hist
calculate histogram
-hist2d, --hist2d
calculate 2-dimensional histogram based on two columns
-nbin value, --nbin value
number of bins to calculate histogram
-rel, --relative
use percentiles for histogram to calculate histogram
-kde, --kde
Use Kernel ⟨http://pktools.nongnu.org/html/classKernel.html⟩ density estimation
when producing histogram. The standard deviation is estimated based on Silverman's
rule of thumb
-cor, --correlation
calculate Pearson produc-moment correlation coefficient between two columns
(defined by -c <col1> -c <col2>)
-rmse, --rmse
calculate root mean square error between two columns (defined by -c <col1> -c
<col2>)
-reg, --regression
calculate linear regression between two columns and get correlation coefficient
(defined by -c <col1> -c <col2>)
-regerr, --regerr
calculate linear regression between two columns and get root mean square error
(defined by -c <col1> -c <col2>)
-v level, --verbose level
verbose mode when positive
Advanced options
-src_min value, --src_min value
start reading source from this minimum value
-src_max value, --src_max value
stop reading source from this maximum value
-fs separator, --fs separator
field separator.
-r startrow [-r endrow], --range startrow [--range endrow]
rows to start/end reading. Use -r 1 -r 10 to read first 10 rows where first row is
header. Use 0 to read all rows with no header.
-o, --output
output the selected columns
-t, --transpose
transpose input ascii vector (use in combination with --output)
-comment character, --comment character
comment character
