Ever wanted to slap someone in the face with an eel? Since a Poisson binomial distributed variable is a sum of n independent Bernoulli distributed variables, its mean and variance will simply be sums of the mean and variance of the n Bernoulli distributions: = ∑ = = ∑ = (−) For fixed values of the mean ( ) and size (n), the variance is maximal when all success probabilities are equal and we have a binomial distribution.

Chapter 8 Poisson approximations Page 2 therefore have expected value ‚Dn.‚=n/and variance ‚Dlimn!1n.‚=n/.1 ¡‚=n/.Also, the coin-tossing origins of the Binomial show that ifX has a Bin.m;p/distribution and X0 has Bin.n;p/distribution independent of X, then X CX0has a Bin.n Cm;p/distribution. program (prog = 2), especially if the student has a high math score. and Jeremy Freese (2006). Cameron, A. C. and Trivedi, P. K. (2009). poisson.test. The predicted zero-inflated model should be considered. Each variable has 200 valid observations and their distributions seem quite exist in the data, "true zeros" and "excess zeros".
