Multi-dimensional histogram

Schiele and Crowley (1996, 2000) have suggested the x2 divergence measure to compare multi-dimensional histograms. In contrast to histogram intersection, this measure does not require a sparse distribution of colors to distinguish between different objects. The Xg-divergence is calculated as... 

Li et al compare different approaches, in the study of the conversion of ethane to methanol. They employ a X weighted histogram analysis method (WFIAM) in order to improve statistics. Minh uses WHAM to develop a multi-dimensional potential of mean force. 

The weighted histogram analysis method was presented by Kumar et al. [90] as an extension of the umbrella sampling method to compute multi-dimensional PMFs. A detailed description of the method can be found in the references [95,...
