Hi, I'm wanting to test for a difference in medians between 2 groups using resampling methods. I found the boot package, but don't really understand how to write the 'statistic' function required as the 2nd argument for the bootstrap test. Thanks if you can help, Paul

Hi Paul, I struggled with the boot package too, and I found this help link very useful: http://www.mayin.org/ajayshah/KB/R/documents/boot.html "Getting started with the "boot" package in R for bootstrap inference". I hope you'll find what you need there ! The second argument for the bootstrap test just tells R on what you want to bootstrap on. Just try the examples in this tutorial... Camille pgseye a ?crit :
