Title: Finding PDF with std deviation, mean and skewness
Post by rainman2354 on Oct 15^th, 2004, 12:07am

I'm stuck on a problem where I am trying to find the probbability density function. Anyone know a formula to get it given values for standard deviation, skewness coefficient, and mean?

I think that to get the exact PDF you will need all the (central?) moments, not just those few derivatives..

At best you can get some approximation. You can probably make a skewed sort of normal distribution
