It is used frequently in risk prediction models. The test assesses whether or not the observed event rates match expected event rates in subgroups of the model population. The Hosmer–Lemeshow test specifically identifies subgroups as the deciles of fitted risk values. Models for which expected and observed event rates in subgroups are similar are called well calibrated. The Hosmer–Lemeshow test statistic is given by: :$H\; =\; \backslash sum\_^\; \backslash frac\; .\backslash ,\backslash !$ Here ''O''''g'', ''E''''g'', ''N''''g'', and ''π''''g'' denote the observed events, expected events, observations, predicted risk for the ''g''th risk decile group, and ''G'' is the number of groups. The test statistic asymptotically follows a $\backslash chi^2$ distribution with ''G'' − 2 degrees of freedom. The number of risk groups may be adjusted depending on how many fitted risks are determined by the model. This helps to avoid singular decile groups. ==References== * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hosmer–Lemeshow test」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
