Re: st: calculate maximum density of normal distribuion

[Nick Bornschein <nick.bornschein@gmail.com>]

Well, no.

The maximum density of a normal distribution of mean = 1 and sd = 2 is 
around 0.2 (looking at the graph) and with mean = 5 and sd = 3 it's 
around 1.125...so it's not always the same when I change the given mean 
and sd.
