No need to use self published sources because Rummel published many articles in peer reviewed journals Therefore it is very likely that Rummel placed this article at his web site because he was unable to publish this concrete material in peer reviewed journals I am afraid I will have to revert your edits if they will be based on this source Anywat you have to separate two things Rummel s theory and Rummel s figures To discuss Rummel s theory with you seriously I would like to know your math background in particular your knowledge of statistics Do you know what factor analysis is With regard to Rummels figures multiple reliable sources agree they are unreliable and inflated Therefore Rummel is fringe for figures
