... and two hours after breaking the glass. In the first hour the breaker would lose, on average, 80 to 90% of the glass transferred to his clothing and, on average, 45 to 70%, of the glass remaining on his clothing in each successive hour until apprehension. Figure 3 shows the model with the same assum ...

Empirical analysis of earthquake-recurrence-interval data has been used to guide the development of statistical models for the earthquake-recurrence processes (Utsu, 1984; Nishenko and Buland, 1987; Ellsworth, 1995; Ogata, 1999). Although limited in scope, presently available recurrenceinterval data ...

Mixture model

In statistics, a mixture model is a probabilistic model for representing the presence of subpopulations within an overall population, without requiring that an observed data set should identify the sub-population to which an individual observation belongs. Formally a mixture model corresponds to the mixture distribution that represents the probability distribution of observations in the overall population. However, while problems associated with ""mixture distributions"" relate to deriving the properties of the overall population from those of the sub-populations, ""mixture models"" are used to make statistical inferences about the properties of the sub-populations given only observations on the pooled population, without sub-population identity information.Some ways of implementing mixture models involve steps that attribute postulated sub-population-identities to individual observations (or weights towards such sub-populations), in which case these can be regarded as types of unsupervised learning or clustering procedures. However not all inference procedures involve such steps.Mixture models should not be confused with models for compositional data, i.e., data whose components are constrained to sum to a constant value (1, 100%, etc.). However, compositional models can be thought of as mixture models, where members of the population are sampled at random. Conversely, mixture models can be thought of as compositional models, where the total size of the population has been normalized to 1.
