A slightly modified multiplier bootstrap procedure for the pre-test of the conditional parallel trends assumption
test.mboot(inf.func, DIDparams, cores = 1)
an influence function
DIDparams object
The number of cores to use to bootstrap the test
statistic in parallel. Default is cores=1
which
corresponds to not running parallel.
