Hello,
I would to fit my data with the following integral:
y(x)= integral F(x,t)*P(t,Sigma)dt
between -Infinity and + Infinity and where P(t,Sigma) is the gaussian distribution with mean value t and sigma.
I tried using the examples given in this forum but I have problem because I need to integrate between - infinity and + Infinity
Could you help me ?
Thanks a lot. |

Of course it's impossible to start integrating at -infinity. Perhaps you can break your expression into +t and -t parts?
integral (0 to inf) {F(x,t)*P(t,Sigma) - F(x,-t)*P(-t,Sigma)} dt

Thanks. What would be the program in order to integrate from - infinity instead of starting at zero.
thanks

Hi,
Would you please see if this post helps? It is about fitting with integral between 0 and infinity.
