- TL;DR Summary
- Let PGF be
$$G_X (t) = E(t^x) = \Sigma P(X=x_i) t^{x_i}$$
and ##G_X (1) = 1##
My questions:
1) What about if t = 2? Is there a certain meaning to ##G_X (2)## ?
2) PGF for uniform distribution is ##G_X (t)=\frac{t(1-t^n)}{n(1-t)}## and for t = 1 ##G_X (1)## is undefined so ##G_X (1) =1## is not true for all cases?
Thanks
