I'm having problems changing the limits of integrations for the standard normal function.
The standard normal function has limits from negative infinity to x, and we know to change this we add a half to the function and make the new limits from 0 to x.
However now I want to change limits that are from positive infinity to x, but am confused on how to change these.
What do I do to the function in order to make this infinity a 0 or another constant?
Thanks
Gino
EDIT:
Here is a link to the picture of the integral of the standard normal function. The only difference for this question is that I have a positive infinity in the lower limit.
