Generate skewed distribution excel
WebSo the answer, using your construct for normal, would be =EXP ( NORMINV (RAND (),Mean,Stdev) ) However that will give you very large values. Next step is to scale the mean and standard deviation. In pseudocode, scaled mean = ln ( m^2 / sqrt ( m^2 + s^2 )) scaled sd = sqrt ( ln ( ( m^2 + s^2 ) / m^2 )) Share Improve this answer Follow WebSyntax.
