hi,
could any kind soul explain what the error
On::none: Message SeriesData::csa not found
means?
it came from the following integral (it's supposed to be a
convolution of a log-gaussian and a power law)
In[26]:= ?f
Global`f
f[n_, s_, b_, x_] := (1*Exp[-(x^2/(2*s^2))])/(s*Sqrt[2*Pi]*n^b*10^(b*x))
In[26]:= Integrate[f[n,s,b,x],x]
1
Integrate[----------------, x]
2 2
b x x /(2 s )
10 E
Out[26]= ------------------------------
b
n Sqrt[2 Pi] s
In[27]:= Integrate[f[n,s,b,x],{x,-Infinity,Infinity}]
On::none: Message SeriesData::csa not found.
Out[27]= 0
this zero seems a bit strange too. i assume that i am doing
something stupid (and that undersatnding the error message might
help).
thanks,
andrew
p.s. it's Mathematica 2.2 for Solaris
