Can anyone tell me what I'm doing wrong?
Well, using EXCEL for a start ;-)
Well, that's why I'm here :)
No - seriously, I can't see at a glance why they differ, and since this distribution has been added recently, a mistake as always possible.
I'll look more closely as soon as I can, but it won't be today (but at least you know you are on my TODO list, and can mail me privately).
Excellent - thanks very much.
PS As a very quick idea - Is the /2 in (1+$C$3)/2 the cause of the difference?
Excel can't calculate the lower limit if I take out the /2. However, if I take out the /2 in the upper limit ((1-$C$3)/2 => (1-$C$3)) then it produces an answer which is closer to the boost answer. For 17 events, Excel now produces 25.50, compared to boost's 25.98. -Paul
