Hi all, I have just uploaded a new package to the ftp site called exact2x2. The package does exact conditional tests for 2x2 tables. Specifically, it does Fisher's exact test and Blaker's exact test (see Blaker, 2000, Canadian Journal of Statistics, 783-798). The motivation for the package is to have inferences from p-values and confidence intervals match as much...

Hi all, I have updated the exact2x2 package which calculates exact conditional tests and the matching confidence intervals for 2x2 tables. The big change in the update is to allow the option paired=TRUE which gives an exact McNemar's test together with odds ratio estimates and confidence intervals. See vignette("exactMcNema...

Hi all, I have updated the exact2x2 package. The update corrects an error that can sometimes occur in the confidence intervals when the number of counts are large and tsmethod="minlike". In addition to fixing the bug, the correction gives a much faster method for calculating the confidence interval. The package gives exac...

Hi friends, I get different values for McNemar's test in R and SPSS. Which one should i rely on when the p values differ. I came across this problem when i started learning R and seriously give up on SPSS or any other proprietary software. Thank u in advance Output in SPSS follows *Crosstab* hsc Total ABN NE ABN tvs ABN Count 40 3 43 Row % 93.0% 7.0%

Hi, I received a bug report for my exact2x2 package that seems to apply to fisher.test in the stats package also. Here is some code which creates the error: >x<-factor(c(0,1,1),levels=c(0,1)) > y<-factor(c(1,1,1),levels=c(0,1)) > fisher.test(x,y) Error in fisher.test(x, y) : 'x' and 'y' must have at least 2 l...

Hi I was wondering whether anyone can help me with this problem....it's been driving me nuts, I've been trying to figure it out for months and months without success!! Basically I have a group of participants who attended 2 experimental sessions a few months apart. I took measures of the way they approach two tasks at Time 1 and the same two tasks at Time 2. I have categorical data (a
