Create series of random numbers fitting a specified distribution, and then analyze them.
Project description
Randalyze - Random Number Generator And Analyzer
What Does Randalyze Do?
Randalyze is a Python module that you can import or use directly from the command line to generate a set of random numbers. These numbers will fit a specified distribution, rather than just being evenly distributed.
It also allows you to analyze a set of numbers, to see which distribution they match.
Installation
Randalyze supports Python 3.8 and later, so you can install it on Windows 7 if you want. It doesn't support Python 2.7.
To install Randalyze, create a virtual environment and use pip
:
pip install randalyze
Usage
Command Line Usage
Generating Random Numbers
The generate
command creates a number of random numbers. The type of generator must be specified - currently the only option is benford
, and the number (or count) of numbers generated is specified with the -c
option.
For example, to generate 100 random numbers with a Benford distribution, the following command line can be used:
randalyze generate -c 100 benford
or, if you're not using an active virtual environment:
python -m randalyze generate -c 100 benford
For detailled parameter descriptions, use:
randalyze --help
randalyze generate --help
Analyzing Numbers
If you have a set of numbers, randalyze
can analyze them and tell you how close to a Benford distribution they are. These numbers may have been generated by randalyze
, or maybe obtained from somewhere else - it really doesn't matter.
So, to analyze an output of 10,000 numbers from the randalyze generate
command, and see whether it matches a Benford distribution to within 10%, use:
randalyze generate benford -c 10000 | randalyze analyze -t 10 benford
And to ensure the numbers in a text file numbers.txt
, with one number per line, fit a Benford distribution:
cat numbers.txt | randalyze analyze -t 10 benford
or use the FILE
parameter:
randalyze analyze -t 10 benford numbers.txt
And to produce the output in JSON format:
randalyze analyze -t 10 --format json benford numbers.txt
Self Testing
You can use randalyze
to analyze the numbers it creates by piping the output of the generate
command into the analyze
command. For example, to check whether 10,000 generated numbers are wihin 10% of a Benford distribution, use:
randalyze generate benford -c 10000 | randalyze analyze -t 10 benford
