Generating 2x2 contingency tables
Hi again, Thank you. I solved my problem by sampling from the multinomial distribution..

Hello R-users, I would like to generate two-way contingency tables with zero in one
cell. I tried to use the function r2dtable but I could not force one cell to have zero value.
r2dtable samples from the conditional distribution of the table given the margins. And with margins fixed AND one cell fixed (to zero) the conditional distribution just puts mass one at the observed table. You may want to sample from a multinomial distribution with one of the parameters fixed to zero. Best, Torsten
Any Idea? Best regards.. Mahmoud [[alternative HTML version deleted]]
