The quasi-binomial isn't necessarily a particular distribution; it describes a model for the relationship between variance and mean in generalized linear models which is ϕ times the variance for a binomial in terms of the mean for a binomial. There is a distribution that fits such a specification (the obvious one - a scaled …

Web7. Working with probability distributions in R. In this Section you’ll learn how to work with probability distributions in R. Before you start, it is important to know that for many standard distributions R has 4 crucial functions: Density: e.g. dexp, dgamma, dlnorm. Quantile: e.g. qexp, qgamma, qlnorm. Cdf: e.g. pexp, pgamma, plnorm. WebJan 3, 2024 · Modeling a Binomial Distribution Using R.
