Hosmer–Lemeshow test (HL test) 是一种统计上的方法,去验证一个风险预测(risk prediction)分类模型是否校准良好 (well calibrated) 个人的感觉:calibrated 的用处是以下几点,第一在概率学上有意义,比如…
Hosmer–Lemeshow test（HL测试）是统计学中的一种方法，用于验证风险预测分类模型是否校准良好。校准良好的模型意味着预测的概率与实际结果一致。HL测试通过比较预期值和观察值来实现这一目标。校准在概率学中尤为重要，因为它确保了预测的准确性和可靠性。例如，如果一个模型预测事件发生的概率为20%，那么...
校准度则是模型拟合优度的指标,衡量的是结局实际发生概率和模型预测概率之间的一致性,体现了模型对绝对风险预测的准确性,常用Hosmer-Lemeshow good of fit test来评估。校准曲线(Calibration Curves)是把Hosmer-Lemeshow拟合优度检验结果的可视化,是一种用于评估在不同分位数上预测概率和观测概率一致性的视觉工具,实际上...

The Hosmer-Lemeshow test results are shown in range AN4:AN6. The HL stat is 6.878106 (as calculated in cell AK14), df = g – 2 = 10 – 2 = 8, and p-value = CHISQ.DIST.RT(6.878106, 8) = .549839. Since this value is larger than α = .05, we have a non-significant resu...
