Hello guys, I am stuck here: How do I make 1000 samples of n = 10 observations from an Exponential distribution and then compute the mean for all those 1000 samples?
The R Commander will do this. See the menus Distributions -> Continuous -> Exponential -> Sample... If you were wanting to normalize the row sums (or investigate the sampling distribution of some other statistic, for that matter) then check out the Sampling Distributions... menu in RcmdrPlugin.IPSUR. Good luck, Jay
Basically I need to prove the Central Limit theorem, which states: http://www.nabble.com/file/p22664113/d175f06cbf200bd52a2c27a2e56dc594.png Where the Sn is sum of random variables, n we have from the question, mu is mean and (sigma)^2 is variance. I am having trouble setting up the function to do this.
