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 … See more Motivation Logistic regression models provide an estimate of the probability of an outcome, usually designated as a "success". It is desirable that the estimated probability of success be close to … See more • Hosmer, David W.; Lemeshow, Stanley (2013). Applied Logistic Regression. New York: Wiley.
