Marsaglia-polar.js

This script generates random numbers along a Normal or Log-normal distribution using the Marsaglia polar method.

There are four functions you can use:

• normalRandom: Generate random numbers that follow a Normal distribution.
• normalRandomInRange: Generate random numbers that follow a Normal distribution but are clipped to fit within a range
• normalRandomScaled: Generate random numbers that follow a Normal distribution with a given mean and standard deviation
• lnRandomScaled: Generate random numbers that follow a Log-normal distribution with a given geometric mean and geometric standard deviation
