Local Asymptotic Normality
In statistics, local asymptotic normality is a property of a sequence of statistical models, which allows this sequence to be asymptotic distribution, asymptotically approximated by a normal distribution, normal location model, after an appropriate rescaling of the parameter. An important example when the local asymptotic normality holds is in the case of i.i.d sampling from a regular parametric model. The notion of local asymptotic normality was introduced by and is fundamental in the treatment of Efficiency (statistics), estimator and test efficiency. Definition A sequence of parametric statistical models is said to be locally asymptotically normal (LAN) at ''θ'' if there exist matrix (mathematics), matrices ''rn'' and ''Iθ'' and a random Coordinate vector, vector such that, for every converging sequence , : \ln \frac = h'\Delta_ - \frac12 h'I_\theta\,h + o_(1), where the derivative here is a Radon–Nikodym theorem#Radon–Nikodym derivative, Radon–Nikodym deriv ...
