Roughly, given a set of independent identically distributed data conditioned on an unknown parameter , a sufficient statistic is a function whose value contains all the information needed to compute any estimate of the parameter (e.g. a maximum likelihood estimate). Due to the factorization theorem (see below), for a sufficient statistic , the probability density can be written as . From this factorization, it can easily be seen that the maximum likelihood estimate of will intera… Webfamous ‘fundamental theorem of Natural Selection’ and exactly what he meant by it.
