同学你好,
LR test是一种用于评估逻辑回归模型拟合度的方法。它基于对数似然度量来描述模型对数据的拟合程度。
The likelihood ratio (LR) test is a method to assess the fit of logistic regression models and is based on the log-likelihood metric that describes the fit to the data.
The LR test statistic is
LR = −2 × (Log-likelihood restricted model – Log-likelihood unrestricted model).
