How to sample data from a distribution
WebIf population is a numeric vector containing only nonnegative integer values, and population can have the length 1, then use y = population (randsample (length (population),k)) or y = datasample (population,k,'Replace',false) instead of y = randsample (population,k). Web21 jun. 2015 · When simulating any system with randomness, sampling from a probability distribution is necessary. Usually, you’ll just need to sample from a normal or uniform distribution and thus can use a built-in random number generator. However, for the time when a built-in function does not exist for your distribution, here’s a simple algorithm.
