WebMay 13, 2024 · The Hosmer-Lemeshow test is a test for goodness of fit in binary classification. It is typically used in the context of logistic regression. ... I'm doing a logistic regression and created a calibration plot. I also conducted a Hosmer-Lemeshow test and got the corresponding chi-square. Is there any relationship between the calibration plot … WebNov 30, 2024 · However, the relation is not totally direct; the Hosmer-Lemeshow binning into groups is not usually shown on the calibration plot (although I think there is more than one way to set it up). So one can't directly connect the workings of the test to the plot.
WebThe accuracy/consistency was evaluated by the Hosmer–Lemeshow test and calibration curve. Internal validation was done using the bootstrap approach. Results: Totally 97 pediatric participants were included in the study and 4 (4.1%) were lost during the follow-up. ORS therapy was effective in 46 children and ineffective in 47 children.
