grosso-modo

random number generator for specified confidence interval note that this uses a gaussian Z as seed and not the usual uniform U to facilitate the generation of correlated variables

Example

import {norm, logn} from 'grosso-modo'

const n = norm(2, 4)(),      // normal distribution with 50% of values between 2 and 4
      l = logn(2, 4, 0.9)(), // lognormal distribution with 90% of values between 2 and 4

API

All distribution take lower and upper bounds along with a probability confidence interval that defaults to 50%.
