random_init_uniform | R Documentation |
Generates random numbers from a finite union of intervals.
random_init_uniform(n, lefts, rights)
n |
An integer, the number of samples to return. |
lefts |
A vector of numbers, must have the same length as |
rights |
A vector of numbers, must have the same length as |
For each sample, a random bin i
is uniformly chosen from 1 through length(lefts)
; if the lefts[i]
and rights[i]
define a finite interval, a random uniform variable is drawn from the interval; if the interval is infinite, a truncated laplace variable with location 0 and scale 1 is drawn. Used for randomly generating initial points for generators of truncated multivariate distributions.
n
random numbers from the union of intervals.
