Definition of Overdispersion. Meaning of Overdispersion. Synonyms of Overdispersion

- In statistics, overdispersion is the presence of greater variability (statistical dispersion) in a data set than would be expected based on a given statistical...
- that the observed variance is greater than the mean; this is known as overdispersion and indicates that the model is not appropriate. A common reason is...
- distribution of it, known as phylogenetic overdispersion (Webb et al., 2002). The reverse of phylogenetic overdispersion is phylogenetic clustering in which...
- linear models. Quasi-likelihood estimation is one way of allowing for overdispersion, that is, greater variability in the data than would be expected from...
- statistics, empirical Bayes methods and classical statistics to capture overdispersion in binomial type distributed data. The beta-binomial is a one-dimensional...
- where a solute comes out of solution in the form of floccules or flakes Overdispersion or statistical aggregation, where the variance of a distribution is...
- biodiversity research for analyzing count data where overdispersion is very common. This is because overdispersion is indicative of biological aggregation, such...
- Compound distributions are useful for modeling outcomes exhibiting overdispersion, i.e., a greater amount of variability than would be expected under...
- probability distributions. If τ exceeds 1, the model is said to exhibit overdispersion. The binomial case may be easily extended to allow for a multinomial...
- subpo****tions (due to spread from different means), and thus exhibits overdispersion relative to a normal distribution with fixed variation σ , {\displaystyle...
