Hi, This is an announcement for a package that has been up on CRAN since March 2006 but was never announced. The package is Mchtest - for Monte Carlo hypothesis tests allowing sequential stopping. The idea is to use the sequential probability ratio test boundaries to stop resampling for a Monte Carlo hypothesis test such as a bootstrap or permutation test. This means that you will take many samples when the p-value is close to...

...t have a good understanding of the various approaches to sequential clinical trials designs, I thought that the gsDesign package seemed very impressive. I also understand that there are several other R packages that relate to sequential clinical trials designs, such as AGSDest , GroupSeq, ldbounds, MChtest, PwrGSD, and Seqmon. Some of these seem fairly comprehensive while others seem to focus on a single approach.   My questions center on the adequacy of SPLUS Seqtrial and the R Packages. I was wondering if there is anyone out there who would be familiar enough with these to comment on their relativ...
