Applied Probability Trust (7 October 2008) EXACT VALUES AND SHARP ESTIMATES FOR THE TOTAL VARIATION DISTANCE BETWEEN BINOMIAL AND POISSON DISTRIBUTIONS JOSE A. ADELL, JOS´ E M. A Among old and interesting results that are related to the Poisson approximation, Le Cam’s inequality (see Le Cam (1960)) provides an upper bound on the total variation distance between the distribution of the sum W = ∑ i = 1 n X i of n independent Bernoulli random variables {X i} i = 1 n, where X i ∼ Bern (p i), and a Poisson distribution Po (λ) with mean λ = ∑ i = 1 n p i. However, this distance is rarely needed or used here, since d TV(V;W) = 1 2 kV Wkprovided that V(X) = W(X), which in concrete situations is often the case. Clearly, it is less likely for the p-coin to be successful than for the p′-coin. However, as far as we know, there are only a few papers devoted to obtain exact values for such probability metrics, even in the most simple and paradigmatic examples.
