Score tests for zero inflation in generalized linear models. (English) Zbl 0971.62037
Summary: The authors develop score tests of goodness of fit for discrete generalized linear models against zero inflation. The binomial and Poisson models are treated as examples, and in the latter case the proposed test reduces to that of J. Van den Broek [Biometrics 51, No. 2, 738-743 (1995)]. Some simulation results and an illustrative example are presented.
