CRIMEMATH NPM Module

This package contains mathematical formulas for users to quickly calculate outputs they need for criminological/criminalistic/public safety research purposes. This package is geared towards students studying these topics but anyone can use this package. There will simply be a learning curve if you are no used to using math in this way.

Contact me at my website if there is a formula you would like me to add to the module.

GENERAL CRIMINOLOGY FORMULAS

//Crime Rate Formula
let result = crimeRate(crimesReported, population);
