发帖数: 46 | 1 it is about how to get the Erlang distribution function. it says:
".... In other words, the probability that n events occur before time x is F
(x), where X is Erlang(n,Ɵ). Equivalently, the probability of AT LEAST
n events occurring before time x in a Poisson process is equal to F(x)."
I really don't understand why the first sentence says n events, where the
second sentence says at least n events. I had been thought about it for
couple of days, still can not get it. :( Can anyone help me out? Thanks a
lot!!! |
