I could use Monte Carlo simulation or the normal approximation when n1 and n2 are greater than, 10, but I figured someone may know how to calculate these exactly. Thanks. Sincerely yours, Mark J.

...hus using extensively the fork and exec syscalls. However, it is surprising for me that the overhead is as high as 20%. My question is about the cost of fork and exec in the new Xen v3? My guess is that they are higher than those published for v1 in Xen Art of virtualization paper.

Hi Lamia, Currently there is no direct InfiniBand access support in the Official Xen trees. You might want to have a look at our Xen-IB implementation. A preliminary version can be downloaded here: http://xenbits.xensource.com/ext/xen-smartio.hg Some information about its design and applications can be...

Is there an equivalent in R to the crosstabs command S-Plus? I've been searching for a while and can't seem to find anything. Thanks. Mark J.

Hi, I am trying to convert a colleague from using SPSS to R, but am having trouble generating a result that is similar enough to a bootstrapped cox regression analysis that was run in SPSS. I tried unsuccessfully with bootcens, but have had some success with the bootcov function in the rms package, which at least generates confidence intervals similar to what is observed in SPSS. However, the

Does anyone know a command to obtain the expected values of residuals under normality? Better yet, is there a command to perform a correlation test for normality (not Shapiro-Wilk Test)? I've looked everywhere, and can't seem to find how to do this. Thanks. Mark J.

Dear List, This problem is more a statistic one than a R one. Any one can recommend me some references website or online paper on maximum likelihood estimation?I'm now working on that,while still doubt how to prove that the estimated parameters are normal distributed. Thanks for your time and help! Best, Ning

Hi, R allows me to run a one sample Wilcoxon test like this: wilcox.test(c(1,3.5,2.1,4,1.5,5), mu=2, exact=TRUE) The function 'wilcoxsign_test' from the package 'coin' should (I suppose) be able to calculate exact p values even if there are ties in the ranks. However, I couldn't find information on how to run a one sample test using 'wilcoxsign_test' like in the

Hi list, Could anyone recommend some good website for formatting R code? For example, when you copy paste R code to gmail and back to R, it loses its format, the dash symbol causes errors. I've had someone used it to format my code here on the list, but can't find it anymore. Mike [[alternative HTML version deleted]]
