Total Shots Ratio: a football analytics library.
Total Shots Ratio (tsr) is a means of expressing the number of shots taken by a team to the number of shots condeded. Theoretically, more successful teams should have higher TSR's.
TSR is a very simple calculation. The number of shots created by a team is divided by the numbers of shot created plus the number of shots conceded.
TSR = (taken / ( taken + conceded))
Install the module with:
npm install tsr
Require the module in your js:
var tsr = require('tsr');
TSR takes two arguments: shots taken + shots conceded. You can pass in either numbers or arrays.
;; // 0.5; // 0.25; // 0.25
