Beta-binomial distribution is a discrete probability distribution. It is basically a Binomial distribution when probability of success at each of the “future” n Bernoulli trials is not fixed but drawn from a Beta distribution. Beta-binomial distribution is used to capture overdispersion in Binomial type distributed data. There are 3 parameters in Beta-binomial: n, the futureContinue reading “Beta-Binomial distribution”

Log-normal distribution
The log-normal distribution is a continuous probability distribution of a positive real random variable, whose logarithm is normally distributed. It is often used to model right-skewed (long right tail), none-negative data. A Log-normal distribution is defined by the locationand scalethat coincide with the mean and standard deviation of the log-transformed normal distribution. As they areContinue reading “Log-normal distribution”
