I am using the PDF for log-normal distribution, which I'm referencing off the wikipedia page:
here. I am integrating from 0 to infinity with my TI-89. It is not giving me 1, as I'd expect from a PDF, but is giving me infinity. Here is how I'm entering it in the calculator (I've tried a few variations):
e^(-((ln(x-1))^2/2))/(sqrt(2*pi)*x)
mu and sigma are one, so it simplifies to this. What is going on :(
Also I just tried integrating from 0 to 12, and it also says infinity. I guess I am doing something wrong :(
Thank you
