I am interested in functions for post-hoc hypothesis testing in linear regression, i.e. to perform t-tests for equality of a single coefficient to a given value, or to perform F-tests for the equality of multiple coefficients (summed) to a given value. I see nothing in the current list of contributions that appears to do that. I am a complete R novice, so am not prepared to write complex functions. Thanks, karen Updegraff -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
