Hi all,
I would like to run a paired t-test with censored data using the NADA
package. Here is an example data set:
data <- data.frame(group=rep(c('a','b'), each=6),
obs=c(2,2,5,7,10,10,5,5,6,8,5,9),
cen=c(T,T,F,F,F,F,F,F,F,F,F,F))
#A two sample t-test can be executed as follows:
library(NADA)
cendiff(data$obs, data$cen, data$group)
Does anybody know how to extend this to conduct a paired t-test based on
the difference between paired observations of groups A and B?
Many thanks,
Jake
