Description

I've noticed that Jacknife is very slow and could benefit by many improvements:

  • better estimation of the missing elements of x by using deleteat! and insertat!
  • parallelization over threads (this is actually trivial to do)
  • having an optional progress bar (new field to Jackknife)
  • Warning users that it takes miuch more than a typical entropy estimat as it computes at least as many entropies as length(x).

Contributor guide

Research direction
Profile the current Jackknife implementation, then implement deleteat! and insertat! for efficient element removal/insertion, use Threads.@threads for parallelization, add a progress bar with ProgressMeter.jl, and add a warning about the heavy computation.
