Thank you all for the helpful comments. Special thanks to Mark Brewer,
David
Spiegelhalter and John Wilkinson for their patience and assistance.
The curly braces are, in fact, present in my actual model (so I think my
mailer must have eaten them - this is also the case for the definition of
N
that John pointed out). My modeling problem is in constraining the "prob"
node to the proper [0,1] range. Since some negative values are returned by
f(Y,t), I will try a linear transformation other than simply division by
an
arbitrarily large constant.
Apologies to all if, as suggested by some, my query was a misuse of the
list.
