Sometimes having problems finding a minimum using optim(), optimize(), and nlm() (while searching for noncentral F parameters)
Hi everyone. I have a problem that I have been unable to determine either the best way to proceed and why the methods I'm trying to use sometimes fail. I'm using the pf() function in an optimization function to find a noncentrality parameter that leads to a specific value at a specified quantile. My goal is to have a general function that returns the noncentrality parameter that

Modifying Internal C Files
Hi All. I want to tweak a few minor things inside of internal C code. I have my Win. XP machine set-up to build packages (including C code), but I'm having problems getting the package to run correctly. In particular, I want to modify a few things inside of pnbeta.c (namely errmax and itrmax), which is what the pbeta() function calls upon when there is a noncentral parameter. I copied the

Including a single function from a package
Hello all. I'm building a package where I want to include a function from two different packages. In particular, I want to include mvrnorm and hyperg_2F1 from MASS and gsl, respectively (but the specific functions do not matter). With what I've tried after reading the "Specifying imports and exports" section from the "Writing R Extensions" manual, I get an error:

Problems with pf() with certain noncentral values/degrees of freedom combinations
Hello all. It seems that the pf() function when used with noncentral parameters can behave badly at times. I've included some examples below, but what is happening is that with some combinations of df and ncp parameters, regardless of how large the quantile gets, the same probability value is returned. Upon first glance noncentral values greater than 200 may seem large, but they are in
