Optimal Number Of Bins is a kernel density estimation for fixed intervals.
Calculation of the optimal number of bins for a histogram.

The bin width ist defined with bw=3.49*stdrobust(1/(n)^1/3)
optNrOfBins The best possible number of bins. Not less than 10 though
This the second version of the function prior available in AdaptGauss
