object 
the model to bootstrap the coefficients from 
R 
the number of bootstrap replicates. 
method 
one of 
ncpus 
the number of CPUs to utilize for bootstrapping. 
cl 
a snow or parallel cluster to use for bootstrapping. 
... 
currently ignored. 
The default method is to use fast and robust bootstrap as described in the paper by M. SalibianBarrera, et al. (see references). The other options are to bootstrap the residuals or to bootstrap cases (observations), but the sampling distribution of the estimates from these methods can be numerically instable and take longer to compute.
