| Feb 16, 2014 at 17:18 | comment | added | Bjørn Kjos-Hanssen | yes, should be 0 | |
| Feb 16, 2014 at 17:13 | comment | added | Sauer | The imaginary component should be zero, right? I'm a little confused because you said "maybe zero" in a previous comment? | |
| Feb 16, 2014 at 17:11 | comment | added | Sauer | Well, I see an increase in the magnitude of the imaginary component with increasing working precision. This tells me that it's likely a bug or some problem with rounding. | |
| Feb 16, 2014 at 17:08 | comment | added | Sauer | Try $r = 0.1$. In both Maple and Mathematica, I see an imaginary component. Since I have Mathematica up at the moment, I find an expectation of: $1.0025 - 3.1372*10^{-11} i$ for $r = 0.1$. The magnitude of the imaginary component appears to increase with additional working precision. | |
| Feb 16, 2014 at 16:57 | comment | added | Sauer | Apologies, my previous comments regarding an imaginary component in the expectation, while unresolved, must be a problem with Maple. I do not see an issue with the derivation of the PDF for $h_2$. | |
