Hello,
See the help page for ?sample.
X <- sample(0:1, 10000, replace = TRUE, prob = c(0.25, 0.75))
Hope this helps,
?rbinom would have been a better answer since simpler, faster,
algorithms are available in that case.
Or even
as.integer(runif(10000) < 0.75)

Hi All,
I want to simulate a random variable X which takes values 1 and 0 with
probabilities 75% and 25% respectively and then repeat the procedure
10000
times.
I am sure this is trivial, I tried to look at the help pages online,
but I
can't quite find it.
Appreciate your help.
Thanks and Regards,
Preetam
