WebbFrom several sources I understand that this can be done using a random sample of size n drawn from a normally distributed population, as follows: t = ( x − m) ( s / n) Where x is the sample mean, m is the mean of the normal distribution (I assume you can just use the standard normal distribution, so m = 0 ?), and s is the sample standard deviation. WebbThe Normal approximation to the Binomial distribution does not perform well when p approaches 0 or 1. To circumvent the problem when n > 300, you can compute the sum …
How to Generating Random Numbers with Specific Distribution ... - SAS
Webb31 aug. 2011 · (In statistics, the random numbers are usually a sample from a distribution such as the uniform or the normal distribution.) You can control the stream by setting the seed for the random numbers. The random number seed is set by using the STREAMINIT subroutine in the DATA step or the RANDSEED subroutine in the SAS/IML language.

The method is simple: you use the RAND function to generate X ~ N (μ, σ), then compute Y = exp (X). The random variable Y is lognormally distributed with parameters μ and σ. executing file on mounted folder
