# Can we use White's reality check to compare two Sharpe ratios?

I read a paper from Ledoit and Wolf that proposes a method to compare two Sharpe ratios and a paper from White that proposes a method to compare $n$ trading rules.

My question is: Can we use White's method to compare two Sharpe ratios? I prefer this method because it's computationally simpler.

Did you see the source code provided by one of the authors of the Ledoit and Wolf paper? –  Bob Jansen Mar 13 '12 at 19:18
Yes i see but there is no kernel estimation for the reality check that i have already code –  rich Mar 14 '12 at 8:19
