A comparison of some curves used for graduating chance distribution."In this paper the principal systems of curves of frequency studied by Pearson, Thiele, Charlier, Edgeworth, Bruns were exhibited. After having outlined the method of perequations of Pearson, the author applied equations of curves of form already known to practical cases relative to typical frequency." p. 28 of: Moore, C. L. E.
