Review of the paper α-Geodesical Skew Divergence
Line 37: in the integral, you have to write the domain ꭓ
Line 71: I think you have to remark at first that you are interested particularly in the Fisher-Rao metric, which is the Riemannian metric induced from the Fisher information matrix, and quote some bibliography
Line 97: in the first line of formula, you forgot the pedices in the Christoffel symbols and in the second member you forgot a sum in the first addend
Line 202: in Taylor’s formula, it is not g’ but g’(ft)
Line 204: in the following formula, it is fuj(t,s) = (1-s)ft + fjs
Line 208: in the formula for I(u), you call hu as gu
Line 212: not “in considered” but “is considered”
Line 230: some parenthesis in the integrals are convenient
Line 240: in the following formulas, f and g need pedices and apices
Line 251: it is not ‖gn‖p ≤ ‖fn(1)‖p but ‖gn‖p ≤ ‖fn(1)‖p + ∑j=1n-1 2-j
Line 254: the second member of the following formula is only fn(n)
Line 255 and line 256: in the limit, it is not fn but fn(n)
Line 257: say better that we can deduce that also fn has limit in the space

Reviewer 3 Report
I have carefully read the manuscript entropy-1187952. The Authors proposed an information geometric generalization of the skew divergence called the α-geodesical skew divergence. They study in detail their properties and computational advantages in comparison to the Kulback-Lieber divergence. The manuscript is rigorously written. In my opinion, it provides an original contribution to the study of information skew divergences. Only comment with respect to the bibliography, perhaps the reference J. Math. Phys. 55, 112202(2014) should be added to the list of references. From my previous observations, I recommend the manuscript for publication in Entropy.Author Response
