How to use dnbinom
WebNegative binomial with many zeros. First I’ll draw 200 counts from a negative binomial with a mean (\(\lambda\)) of \(10\) and \(\theta = 0.05\).R uses the parameterization of the negative binomial where the variance of the distribution is \(\lambda + (\lambda^2/\theta)\).In this parameterization, as \(\theta\) gets small the variance gets big. Using a very small value … WebAn alternative parametrization (often used in ecology) is by the mean mu (see above), and size, the dispersion parameter, where prob = size/ (size+mu). The variance is mu + …
