11.2.1.3. astroML.density_estimation.knuth_bin_width¶

astroML.density_estimation.
knuth_bin_width
(data, return_bins=False, disp=True)[source]¶ Deprecated since version 0.4: The knuth_bin_width function is deprecated and may be removed in a future version. Use astropy.stats.knuth_bin_width instead.
Return the optimal histogram bin width using Knuth’s rule [Rc52d530680fe1]
 Parameters
 dataarraylike, ndim=1
observed (onedimensional) data
 return_binsbool (optional)
if True, then return the bin edges
 Returns
 dxfloat
optimal bin width. Bins are measured starting at the first data point.
 binsndarray
bin edges: returned if return_bins is True
Notes
The optimal number of bins is the value M which maximizes the function
where is the Gamma function, is the number of data points, is the number of measurements in bin .
