R commands
2 messages · Jameshutton25@aol.com, Ben Bolker
The first two are pretty basic: #1: x <- rnorm(20) #2: x[x<0] <- 0 #3 is poorly defined. Do you want the estimate of the mean and s.d. of the initial (non-truncated) distribution? I think this might be doable, but someone (preferably you) would have to try to work out the details ... this is a statistical question, not an R coding question. which[x<=0] Ben Bolker

I would like to know how to do the following commands on R: 1) Choose 20 random numbers modelled on the normal distribution. 2)Any of these numbers that are negative to change them to ZERO. 3)Perform a command that will enable me to find the maximum likelihood (the true mean of the distribution). If any of the numbers are zero i need to know which ones they were if possible. Thank you very much for your. I look forward to hearing from you.
