random number generator for specified confidence interval
npm install grosso-modorandom 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
``javascript
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
`
All distribution take lower and upper bounds along with a probability confidence interval that defaults to 50%.
