[R] Plackett-Dale Model in R

[Spencer Graves]

      I'm not familiar with the Plackett-Dale model, and 
RSiteSearch("Plackett-Dale") produced nothing.  Google led me to an 
article on "Plackett-Dale Inference to Study Inheritance" 
(http://doclib.uhasselt.be/dspace/bitstream/1942/466/1/molg23.pdf#search=%22Plackett-Dale%22).  
This article discusses parameter estimation to maximize a 
pseudo-likelihood for a "Plackett-Dale distribution", defined in other 
references.  If you can write a function to compute the Plackett-Dale 
distribution, it should not be too difficult to maximize it (or minimize 
the negative of its logarithm).  From that you should be able to get 
Wald approximate confidence intervals, likelihood ratio tests, etc. 

      However, unless it's available under some other name, it looks to 
me like it's not included in any current CRAN package. 

      I know this is not what you wanted, but I hope it helps.
