WebbAfter normalization, we calculate the entropy: H = − ∫ 0 1 p ( x) log ( p ( x)) d x ∼ − ∑ i p i log ( p i) ⋅ 1 N. As N → ∞ this gives an entropy which is solely related to the distribution shape and does not depend on N. For small N, the difference will depend on how good the Riemann sum approximates the integrals for given N.
