Detailed Description

Base class for single-variate distributions that cache sufficient statistics.

Sufficient statistics are one or more statistics whose values are sufficient to describe the entire distribution. For the joint probability of many independent draws from a distribution, the set of all drawn values is a sufficient statistic, but minimally sufficient statistics (such as the mean and variance for a joint normal distribution) often exist, permitting one-time calculation and efficient use of memory.

Children must overload the following methods:

  • IMP::isd::OneDimensionalSufficientDistribution::do_update_sufficient_statistics()
  • IMP::isd::OneDimensionalSufficientDistribution::do_get_sufficient_statistics()
  • IMP::isd::OneDimensionalSufficientDistribution::do_evaluate()
