Dear all, I am trying to simulate from discrete uniform distribution. But I could not find any in-built code in R. Could anyone help me please? Thanks in advance for the time and help. Cassie [[alternative HTML version deleted]]
Hi: Suppose X has a discrete uniform distribution on the sample space S = {0, 1, 2, ..., 9}. Then a random sample of size 100 from this distribution, for example, would be dus <- sample(0:9, 100, replace = TRUE) # Checks: table(dus) lattice::barchart( ~ table(dus), xlim = c(0, 20)) The sample space comprises the first argument of sample(), the sample size is the second argument, and the replace = TRUE argument allows an element of the sample space to be selected more than once.

Hi Also , same problem to create discrete uniform Distribution , But sample () and runif() not useful to generate discrete uniform . Ex:> u<-round(runif(10*10,min=1,max=10),0)> table(u)u 1 2 3 4 5 6 7 8 9 10 6 10 9 10 14 6 11 14 12 8 Not useful for large number OR # for generate large number dus <- sample(0:9, 100, replace = FALSE) Error in base::sample(x, size, replace = replace, prob = prob, ...) : cannot take a sample larger than the population when ''replace = FALSE'' #### DO you have any suggestion my question ? Need to generate 1000*10 number from 1:250 with discrete uniform distribution ? Regards, Serdar [[alternative HTML version deleted]]
If you wanted a discrete uniform from 1-10 use: ceiling(10*runif(1)) if you wanted from 0-12, use: ceiling(13*runif(1))-1 -- View this message in context: r.789695.n4.nabble.com/Simulation-from-discrete-uniform-tp3434980p3939694.html Sent from the R help mailing list archive at Nabble.com.
