WebHere we suggest two types of contributions to robustness checks: (1) increasing the number of feasible robustness checks by identifying key analytical choices in code scripts and (2) justifying and testing reasonable specifications within the set of feasible checks. WebOct 1, 2009 · Heritier and Ronchetti (1994) introduce robust tests for a general parametric model, which includes logistic regression. Cantoni and Ronchetti (2001) define robust deviances based on generalizations of quasi–likelihood functions and propose a family of test statistics for model selection in generalized linear models.
