Hello list. I need help (e.g., a reference, code, package, etc.) in calculating the joint entropy of many variables (some sure highly mutually-informative and some not). Is there anyone here who knows a computationally-efficient solution (such as an R package)? I appreciate you help ... Best, Reza [[alternative HTML version deleted]]

Hi R-help, I have a database of 10 students who have written an overall of 78 essays. The challenge? I would like to identify who wrote the 79th essay. Has anybody used R in this context? Even if not, would you suggest me which pattern recognition technique I might possibly apply? Thanks a lot and regards, Tom --------------------------------- [[alternative HTML version

Dear R-users, I want to check if certain values are from random distribution, that includes values between 0-1. So, it is not really normal even though shapiro.test says it is highly normal... Can I do something like this and think that the values given are right. z.test is from package TeachingDemos. -------------------------------------------------------------------------------
