MATHEMATICA STATISTICS PACKAGES - DISCRETE and CONTINUOUS DISTRIBUTIONS I have come across the following problem while using the Statistics Packages : Continuous Distributions and Discrete Distributions. PDF[ NormalDisribution[0,1], {0,1} ] will give the standard normal pdf evaluated at 0 and 1 - as you would expect, BUT PDF[ PoissonDistribution[1], {0,1} ] returns only some logical checking. The problem seems to be the { } since PDF[ PoissonDistribution[1], 1 ] is fine but PDF[ PoissonDistribution[1], {1} ] fails. Does anyone have a fix for this? Many thanks Iain Currie
