This is a R package for rapid evaluation of extremely small p-value for resampling-based test (EXPERT). The stochastic approximation Markov chain Monte Carlo algorithm is adopted. The new procedure can be used easily for estimating the p-value for any resampling-based test. Numerical simulations demonstrate that the proposed procedure can be 100 to 500,000 times as efficient (in term of computing time) as the standard resampling-based procedure when evaluating a test statistic with a small p-value (e.g., less than 1e-6 ).
