WebbStata’s basic PRNG is runiform(), which takes no arguments (but the parentheses must be typed). Its maximum value is 1 2 32. As mentioned, all other PRNGs are transformations of that produced by the uniform PRNG. To draw uniform values over a different range: e.g., over the interval [a;b), gen double varname = a+(b-a)*runiform() WebbSeveral built-in random-number functions such as runiform(), rbeta(a,b), rbinomial(n,p), rchi2(df), etc., are available to generate a random sample in Stata 10 and later versions. However, if a sample is to be drawn from any other distribution function, an inverse cumulative distribution function method must be used to apply an
