Re: [R] Robust variance estimation with rq (failure of the bootstrap?)

variance estimate, but that alone isn't evidence to favor one over the other. Also, I can't justify (to myself) why skew would hamper the quality of bootstrap variance estimates. I wonder how it affects the sandwich variance estimate... Best, Matt On Mon, 2011-02-28 at 17:50 -0600, James

Re: [R] non-ascii characters in R output

OK, looks like my web browser does render non-ascii characters output by R when it's given the encoding explicitly. This works for me: . So that's another solution, but not a general one. -Matt On Fri, 2011-02-18 at 12:47 -0600, Matt Shotwell wrote: > All, > > I'd like
