I am trying to reproduce the results given on this site: http://support.sas.com/ctx/samples/index.jsp?sid=491&tab=output This is a problem from a text by Alan Agresti on Categorical Data Analysis that deals with baseball teams. The software I am using is JMP (by SAS). I think I have entered all the data correctly but everytime I try to run the analysis I get different coefficient estimates. Can someone provide help in using this particular software to correctly run a Bradley-Terry model on this data? I also have minitab available but would like to use JMP.
