hmm. I am not sure what you mean exactly. In my case i've got following
function:
def pdf(x,s1,s2,p):
return
(p/(math.sqrt(2*math.pi*s1**2))*numpy.exp(-((x-0)**(2)/(2*s1**(2)))))+((1-p)/(math.sqrt(2*math.pi*s2**2))*numpy.exp(-((x-0)**(2)/(2*s2**(2)))))
and s1,s2 and p are varying... so i have a list like
123, 3215, 0.3
152, 2351, 0.4
521, 4351, 0.6
...
for these three parameters. So the resulting curves are probably intersecting
each other and are of different shape.
so two questions:
1) what is the best way to supply this list to produce the single curves (about
10)
2) how can I do the fill between to get the "range" of the curves. Maybe you
can give me a more detailed example.
Thanks
