rMultinom
Generate Multinomial Random Variables with Varying Probabilities
Description
Given a matrix of multinomial probabilities where rows correspond to observations and columns
to categories (and each row sums to 1), generates a matrix with the same number of rows as has
probs and with m columns. The columns represent multinomial cell numbers, and within a row
the columns are all samples from the same multinomial distribution. The code is a modification of
that in the impute.polyreg function in the MICE package.
Usage
rMultinom(probs, m)
Arguments
probs
matrix of probabilities
m
number of samples for each row of probs
Value
an integer matrix having m columns

Examples
set.seed(1)
w <- rMultinom(rbind(c(.1,.2,.3,.4),c(.4,.3,.2,.1)),200)
t(apply(w, 1, table)/200)
