A suite of tools for command line analytics

# Veld

Veld is a command line processor for multi-dimensional numeric data streams. It can compute basic univariate statistics such as the mean or the variance of a stream of numbers, process the stream by computing logarithms or rounding, or create visualizations of the data stream, among other functionality. Similar projects in this space include st and datamash. What sets Veld apart from these projects is that it also has support for plotting.

## Installation

Veld is available on PyPI:

$pip install veld ## Usage Currently Veld includes the following commands: usage: veld [-h] [-V] [--debug] command ... Below are the available Veld commands. Use veld help <command> to learn more about each command. univariate statistics: sum Sum the values in the data stream mean Find the mean (average) of the values in the data stream mode Find the mode of the values in the data stream median Find the median of the values in the data stream stdev Compute the standard deviation of the input stream variance Compute the variance of the input stream quantile Find the given quantile for the data in the stream trimmed-mean Compute the trimmed mean for data in the stream summary Print a summary with commonly-used statistics extreme values and counts: min Find the minimum of the values in the data stream max Find the maximum of the values in the data stream count Count the number of values in the data stream frequency Print a frequency table of unique values in the stream filtering values: lt Keep only inputs that are less than a given threshold le Keep only inputs that are less than or equal to a given threshold gt Keep only inputs that are greater than a given threshold ge Keep only inputs that are greater than or equal to a given threshold eq Keep only inputs that equal a given value ne Keep only inputs that are not equal to a given value math operators: log Compute the logarithm of the input stream round Round the floating point values in the input stream cumsum Compute the cumulative sum of the input stream product Compute the product of values in the data stream add Add number to values in the stream subtract Subtract number from values in the stream multiply Multiply values in the stream by number divide Divide values in the stream by a number modulo Compute the remainder of values in the stream plotting: lines Show line plots of the input data scatter Show a scatterplot of two-dimensional data histogram Plot a histogram of the values in the data stream barcount Create a histogram with bars for all unique values in the stream other: paired-ttest Perform a paired t-test on two-dimensional data pass Pass an input stream through Veld For more information about Veld, visit: https://github.com/GjjvdBurg/Veld For example:$ seq 10 | veld sum

## Notes

Author: Gertjan van den Burg.

Why "veld"? Veld is built on top of wilderness, and it's short and didn't conflict with any tab completions I have :)

Veld is a continuation of cli stats.
