i looked up the definition of “skewed” when it comes to normal distributions.
i hope this is right -

q)\l stat.q
q){s:x%sqrt 1+x xexp 2;b:sqrt 1-s xexp 2;u1:(s*u0:nor y)+b*nor y;u1*signum u0}[skew:9;n:5]

JackPossibly the better word to look at is Kurtosis for the understandingof Skew, and how they are used in probability theory: they are 4th and3rd degree functions carrying on from the 2nd and 1st degree functionsof Deviation and Mean. Skew is a measure of "centerness and Kurtosisis for peakedness…greg~krsnadas.org–from: Jack Andrews to: Kdb+ Personal Developers date: 13 December 2012 00:23subject: [personal kdb+] skewed normali looked up the definition of “skewed” when it comes to normaldistributions. i hope this is right -q)\l stat.qq){s:x%sqrt 1+x xexp 2;b:sqrt 1-s xexp 2;u1:(su0:nor y)+bnory;u1*signum u0}[skew:9;n:5]0.2306224 0.5105478 0.09525914 0.751213 1.335868from here: http://stackoverflow.com/questions/4643285/how-to-generate-random-numbers-that-follow-skew-normal-distribution-in-matlabta, jack.
