How can I generate a positive random number list with specified mean and SD?
I know how to do it with rnorm in R but it is not positive since it sampled from a normal distribution, if I'm right.
My preferred language is matlab but a script in R is Ok too.
It really depends on the underlying distribution.
R = normrnd(mu,sigma) you can generate normal distributed random numbers with specified mean and standard deviation.
R = lognrnd(mu,sigma) generates lognormal distributed random numbers.
You can also take a look at this where you can specify the distribution.
Just make sure that you check if it really is positive, e.g.
mu = 10; sigma = 1; R = normrnd(mu,sigma,1,500); %R(R<=0) = resample
