Maximum Entropy distributions on the circle<br />

with given cross-moment.<br />

J. C. S. de Miranda IME/USP<br />

We determine the maximum entropy distribution on the circle, D = {(x, y) ∈ R 2 : x 2 + y 2 ≤ 1},<br />

i.e., we determine the probability density function of the bivariate random vector (X, Y ) whose<br />

image is contained in D, under the following moment and cross-moment restrictions: EX = 0,<br />

EY = 0 and EXY = m, for an arbitrary real constant m.<br />

Keywords: Maximum Entropy; Calculus of Variations; Bessel Functions<br />
