You can do the wild bootstrap and wild cluster bootstrap by running the following code. (Warning! Don't run it except that you have at least 50 cores!)
iB = 5000 # the number of repetitions in the bootstrap
library(snowfall)
pstr = WCB_LinTest(use=pstr,iB=iB,parallel=T,cpus=50)
It takes a long long time to run the bootstrap. This function is developed for those who work on some super-computation server with many cores and a large memory. Note that you will have to attach the "snowfall" package manually.
