WebMar 24, 2015 · The Conway-Maxwell-Poisson (CMP) distribution is a natural two-parameter generalisation of the Poisson distribution which has received some attention … In probability theory and statistics, the Conway–Maxwell–Poisson (CMP or COM–Poisson) distribution is a discrete probability distribution named after Richard W. Conway, William L. Maxwell, and Siméon Denis Poisson that generalizes the Poisson distribution by adding a parameter to model … See more The CMP distribution was originally proposed by Conway and Maxwell in 1962 as a solution to handling queueing systems with state-dependent service rates. The CMP distribution was introduced into the statistics literature … See more The CMP distribution is defined to be the distribution with probability mass function where : See more Many important summary statistics, such as moments and cumulants, of the CMP distribution can be expressed in terms of the normalizing constant $${\displaystyle Z(\lambda ,\nu )}$$. Indeed, The probability generating function is See more There are a few methods of estimating the parameters of the CMP distribution from the data. Two methods will be discussed: weighted least squares and maximum likelihood. The weighted least squares approach is simple and efficient but lacks precision. … See more For general $${\displaystyle \nu }$$, there does not exist a closed form formula for the cumulative distribution function of $${\displaystyle X\sim \mathrm {CMP} (\lambda ,\nu )}$$ See more For general values of $${\displaystyle \nu }$$, there does not exist closed form formulas for the mean, variance and moments of the … See more When $${\displaystyle \nu }$$ is an integer explicit formulas for moments can be obtained. The case $${\displaystyle \nu =1}$$ corresponds to the Poisson distribution. … See more death article
