Speeding Up Non-Parametric Bootstrap Computations for Statistics Based on Sample Moments in Small/Moderate Sample Size Applications
Fig 1
Comparison between the data re-sampling approaches and the vectorized multinomial sampling bootstrap, in the American law school data.
Panel a compares the approach’s time expenditures. Panels b, c and d compare, respectively, the computation time ratio of the “for loop”, “R/bootstrap” and “R/boot” approaches against the vectorized bootstrap. The bottom panels present the distributions generated with B = 1,000,000.
