More multinomial type integrals over the hypercube
As I said the $x_i^2$ gets in the way. If is was just two multinomials, one to power $k$, the other to power $m$, there would be no problem, you would get $\exp(tx + sx)$ and everything would work out nicely as before. Perhaps I have missed something though. How do you intend to use the integral of $\exp(tx^2 + sx)$ (which has no closed form solution as far as I am aware) taken to the power of $n$ to efficiently compute the answer? |

A Book You Would Like to Write
How about you just apply Hofstadter's Law: "It always takes longer than you expect, even when you take into account Hofstadter's Law." |

When is the function of a median closer to the median of the function than the mean of the function is to the function of the mean?
Do you mean to take absolute values? As in $|\mu (f(x)) - f(\mu (x))| > |m (f(x)) - f(m (x))|$? |

Sequential sampling of Gaussian and von Mises-Fisher Random Variable
I like the updated part of this question +1. I recommend deleting the first part (However, don't do this if you have some specific reason not too). If you don't mind me asking, in what application does this problem occur? Also, what justifies your use of the von Mises Fisher distribution here? |

Nonlinear circle fit with known radius
There is a big literature on this. Typing 'circle fitting' into google with give you a lot of resources. Most of the approaches I know of deal with estimating both the center and the radius, but they could easily be adapted to estimate just the center if that is what you want. Your question is probably more appropriate for CrossValidated stats.stackexchange.com/questions. You might have better luck there. |

Oh yes! I much prefer Herman Wouk's ryhming version ''When in danger or in doubt, run in circles, scream and shout'' anyway. Thanks! |

Estimating direction from a distribution on a circle
I think, due to the symmetry, it essential does act in a linear way. I'm pretty sure I can describe very accurately how well your estimator will work. I'll post this as an(other) answer a bit later. |
