2. Hosmer–Lemeshow test - Wikipedia

   en.wikipedia.org/wiki/Hosmer–Lemeshow_test

   The Hosmer–Lemeshow test is a statistical test for goodness of fit and calibration for logistic regression models. 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.

3. Likelihood-ratio test - Wikipedia

   en.wikipedia.org/wiki/Likelihood-ratio_test

   In statistics, the likelihood-ratio test is a hypothesis test that involves comparing the goodness of fit of two competing statistical models, typically one found by maximization over the entire parameter space and another found after imposing some constraint, based on the ratio of their likelihoods.

   The goodness of fit of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between ...

5. Regression validation - Wikipedia

   en.wikipedia.org/wiki/Regression_validation

   One measure of goodness of fit is the coefficient of determination, often denoted, R 2. In ordinary least squares with an intercept, it ranges between 0 and 1. However, an R 2 close to 1 does not guarantee that the model fits the data well. For example, if the functional form of the model does not match the data, R 2 can be high despite a poor ...

9. Deviance (statistics) - Wikipedia

   en.wikipedia.org/wiki/Deviance_(statistics)

   In statistics, deviance is a goodness-of-fit statistic for a statistical model; it is often used for statistical hypothesis testing.It is a generalization of the idea of using the sum of squares of residuals (SSR) in ordinary least squares to cases where model-fitting is achieved by maximum likelihood.
