PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

A slight error in Equation 6

Hunter Moseley   (2012-10-26 17:22)  University of Louisville

There is a slight error in Equation 6 in the two summation terms.

The summation should be for y = 0; y ≤ j and x = 0; x ≤ i with the following condition (y ≠ j or x ≠ i) that must be satisfied as well. It is easier to describe this summation with a single summation term which includes the conditional, which I have tried to represent below given the limitations of this editor:

y ≤ j; x ≤ i; y ≠ j or x ≠ i

y = 0; x = 0
