Gaussian-integrate.

Can anyone tell me how I can integrate the area under a gaussian distribution? Under a particular portion of it. Also, when I multiply a gaussian by another function, how do I integrate that. There appears to be no analytical solution to the integral of a gaussian function.
Thank you. |

Are there any ways of doing this without resorting the maple/mathematica or other software? Surely there must be some means of doing it using a series expansion?
Thanks Pratap, New Name. |

I think you can integrate the area under a gaussian distribution by substitution and multiply twice. I saw this trick problem at some Calculus text book.

Area under a gaussian is called an error function. Tabulated values are available anywhere. For a finite range of integration, use the sum/difference between two error function.

When you say the sum/difference between two error functions, do you mean to use the Cumulative distribution function which is the area under the gaussian? This CDF contains the erro function. Thanks.

Yes, thats what it is called when doing probability
