SVD of complex matrices
Yudi Pawitan · Feb 6, 2001 · r-help

You can do this 'by hand' using eigen(), since it can take complex matrices. If X is a complex matrix, the svd computes the eigenvalue-eigenvectors of X^*X and XX^*, where X^* is the conjugate-transpose of X. (Set...

Yudi Pawitan · Mar 31, 2000 · r-help

Dear R-helpers, I'm learning how to compile R packages with fortran routines and use the acepack source as an example. After some hiccups (Guido told me about the need to set make_mode=UNIX) I got to the...

Goodness of fit to Poisson / NegBinomial
Yudi Pawitan · Feb 7, 2001 · r-help

I had a very similar example before. This is for Mark's data: (the last frequency is for k>= 5). (Mark should be happy with the neg-binomial fit.) -YP- x_ c(70, 38, 17, 10, 9, 6) kk_ 0...

exact test for large tables. Was: [R] unexpected R crash - again
Yudi Pawitan · Aug 26, 2000 · r-help

If you have an actual large table to analyse, rather than trying to solve the space problem, you may want to consider a MonteCarlo implementation of the exact test. Very easy to implement in R. See, for example, Lange's...
