MATHEMATICA - STATISTICS - DISCRETE & CONTINUOUS DISTRIBUTIONS
I have managed to answer part of my question of two days ago - with the help of Stan Wagon's book.
The problem was that the function PDF has
Attributes[ PDF ] = {}
My problem goes away if you set
Attributes[ PDF ] = { Listable }
HOWEVER, this does not explain why, with Attributes[ PDF ] = {},
PDF[ NormalDistribution[0,1], {1} ]
works while
PDF[ POissonDistribution[1], {1} ]
does not!!
A final point - it does seem perverse to have the Attributes of PDF set to {}. This seems wrong-headed
to me.
