Crystal sci-calc

Sci-calc is a CLI based collection of utilities for scientific data analysis written in Crystal.

Available utilities:

Building

Install crystal compiler.

Then:

git clone https://github.com/heric06/sci-calc
cd sci-calc/
shards build --release
### Optional
sudo cp ./bin/sci-calc /usr/bin/

Usage

Useful for things like this:

egrep -o '[0-9](|\.[0-9])' path/to/numbers_sep_by_commas.csv | sci-calc your-sub-command

Use sci-calc your-sub-command --help for option list.

Auto-correlation

Calculates statistical correlation with itself.

Average

Calculates average of numerical data.

Correlation

Calculates statistical correlation of two or more numerical series. Needs at least 2 series.

  • Q: "More series?"
  • A: "If more than two series are given, sci-calc will calculate correlation between each binary combination"

Histogram

Distribuition of numerical data.

Calculates histogram and outputs elements frequencies in range left-right of each file. If no such files are given, reads standard input.

Left and right limiters must be less than min and greater than max, respectively, but by default they are set to min - 1e-7 and max + 1e-7. Crystal supports scientific notation, so that you can call sci-calc like this: sci-calc histogram --bins 10 --norm --left -1e-6 /path/to/file.whatever

Standard Deviation

Sum

Variance
