Hi All,
What is the R function for computing multinomial distribution, e.g. f(2,1,3;
2/9, 1/6, 11/18, 6)?
That is, a total of 6 trials, event 1's p1=2/9, x1=2, event 2's p2=1/6, x2=1,
and event 3's p3=11/18, x3=3.
thanks,
Johnny

. But for
multinomial events, is there a similar function in R?
thanks

R Has an extensive Help system which you should learn to use.
help.search('multinomial')

Jim: sample() is wrong -- it gives random samples, not probabilities.
