Right now I am able to create a RANNOR distribution only.<BR /> <BR /> Right now the code reads:<BR /> VALUE=abs(int(4+sqrt(26)*rannor(10)))<BR /> <BR /> But I would like the VALUE to be pulled from a skewed distribution with median/mean and mode value, instead of this normal distribution.<BR /> <BR /> Thank you.
