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.    is a rural quarter located in the borough Harburg of Hamburg, Germany near the Lower Saxony border.
