If your outcomes are discrete counts, then Poisson regression or negative binomial regression can be used. Remember that the Poisson distribution assumes that the mean and variance are the same.

WebThe outcomes of a binomial experiment fit a binomial probability distribution. The random variable X = the number of successes obtained in the n independent trials. The mean, μ, and variance, σ2, for the binomial probability distribution are μ = np and σ2 = npq. The standard deviation, σ, is then σ = n p q.
