Dear all,
I would like to generate N random numbers with a given probability and
condition but I'm not sure how to do this.
For example, I have N = 20 and the vector from which to choose is seq(0, 10,
1). I have tested:
x <- sample(seq(0, 10, 1), 20, replace=TRUE, prob=rep(0.28, times=length(seq(0,
10, 1))))
But I don�t know how to put the condition sum(x) <= max(seq(0, 10, 1)).
Many thanks for your time
Nell
Maybe the paper "Acceptance–Rejection Sampling from the Conditional
Distribution of Independent Discrete Random Variables, given their Sum",
Statistics 34, pages 247-257, by Leif Nilsson and myself (2000) is relevant?
