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
