WitrynaIt has been reported in the statistics literature that rare events are difficult to predict [see King and Zeng (2001) and others]. In Weiss (2004), it is pointed out that with imbalanced datasets, the learning algorithms are biased in favor of the class priors. Witrynaset. Since the pseudo-data have an event rate of 0.5, Firth-type penalization leads to overestimation of predicted probabilities in case of rare events. The present paper proposes two simple, generally applicable modifications of Firth-type multivariable logistic regression in order to obtain unbiased average predicted probabilities.
Witryna25 lut 2024 · The logistic regression (LR) model for assessing differential item functioning (DIF) is highly dependent on the asymptotic sampling distributions. However, for rare events data, the maximum likelihood estimation method may be biased and the asymptotic distributions may not be reliable. In this study, the performance of the … http://docs.zeligproject.org/articles/zelig_relogit.html

There are lots of examples for logistic regression. Some example code would be wonderful as I am newish to R. It seems that the logistf package can work for firth's correction in logistic ...
Witryna30 cze 2024 · Firth's logistic regression has become a standard approach for the analysis of binary outcomes with small samples. Whereas it reduces the bias in maximum likelihood estimates of coefficients, bias towards one-half is introduced in the predicted probabilities. ...
