Package: veld
VeldVeld 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 includestanddatamash. What sets Veld apart from
these projects is that it also has support for plotting.InstallationVeld is available on PyPI:$ pip install veldUsageCurrently 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

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

didn't conflict with any tab completions I have :)Veld is a continuation ofcli stats.
