 Aug 13 answered Point-wise error estimate in polynomial regression Jul 28 revised More multinomial type integrals over the hypercube deleted 114 characters in body Jul 28 comment 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?

Do you mean to take absolute values? As in $|\mu (f(x)) - f(\mu (x))| > |m (f(x)) - f(m (x))|$? Dec 6 comment 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? Dec 1 comment 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. Oct 17 revised Estimating direction from a distribution on a circle fixed typos Oct 16 comment Estimating direction from a distribution on a circle Oh yes! I much prefer Herman Wouk's ryhming version ''When in danger or in doubt, run in circles, scream and shout'' anyway. Thanks!
