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
