Hi Hiroshi, Why do you call it a static bonus? If n increases with the number of simulations, the effect of the bonus term still fades away. Perhaps the interesting part is in fading out more slowly than with ordinary priors (i.e., by 1/sqrt(n) instead of 1/n)? BR, Erik BTW Nicks original

Hi Hiroshi, I would interpret your results as K=600 is to big, Detlef P.s. this would be consistent with my results Am Sonntag, den 23.11.2014, 10:20 +0900 schrieb Hiroshi Yamashita: Hi Erik, Perhaps the interesting part is in fading out more slowly than with ordinary priors (i.e., by
