Local Asymptotic Normality
In statistics, local asymptotic normality is a property of a sequence of statistical models, which allows this sequence to be asymptotically approximated by a normal location model, after a 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 . Definition A sequence of parametric statistical models is said to be locally asymptotically normal (LAN) at ''θ'' if there exist matrices ''rn'' and ''Iθ'' and a random 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 derivative, which is a formalised version of the likelihood ratio, and where ''o'' is a type of big O in probability notation. In other words, the local likelihood ratio must converge in distribution to a normal random variable whose mean is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
