We propose a generalization of the wild bootstrap of Wu (1986) and Liu (1988) based upon perturbing the scores of M …-estimators. This "score bootstrap" procedure avoids recomputing the estimator in each bootstrap iteration, making it substantially less … costly to compute than the conventional nonparametric bootstrap, particularly in complex nonlinear models. Despite this …

total variation distance between a bootstrap distribution and the normal distribution parameterized by the point estimate … sample of recent empirical articles that use a bootstrap for inference, we find that the conventional normal approximation is …
