This is a continuation of the author’s paper “Convexity properties of some entropies”, published in Raşa (Results Math 73:105, 2018). We consider the sum $$F_n(x)$$ Fn(x) of the squared fundamental Bernstein polynomials of degree n, in relation with Rényi entropy and Tsallis entropy for the binomial distribution with parameters n and x. Several functional equations and inequalities for these functions...
