...what different assumptions do to my confidence intervals is to run a quick nonparametric bootstrap, just to get a feel for how asymmetric the distribution of any estimates might be. At the moment, I'm also interested in doing that on some historical data to evaluate some proposed estimators for interlab studies. boot() is pretty good, but it's obvious that with such small sets, there aren't really many distinct resampled combinations (eg 92378 for 10 data points). So I'm really resampling from quite a small population of possible bootstrap samples. Its surely more efficient to generat...

I am looking at MM-estimates for some interlab comparison work. The usual situation in this particular context is a modest number of results from very expensive methods with abnormally well-characterised performance, so for once we have good "variance" estimates (which can differ substantially for good reason) from most labs. But ther...
