Testing for zero-modification in count regression models
Count data often exhibit overdispersion and/or require an adjustment for zero outcomes with respect to a Poisson model. Zero-modified Poisson (ZMP) and zeromodified generalized Poisson (ZMGP) regression models are useful classes of models for such data. In the literature so far only score tests are used for testing the necessity of this adjustment. For this testing problem we show how poor the ...
متن کاملComparison of Wald, Score, and Likelihood Ratio Tests for Response Adaptive Designs
Data collected from response adaptive designs are dependent. Traditional statistical methods need to be justified for the use in response adaptive designs. This paper generalizes the Rao’s score test to response adaptive designs and introduces a generalized score statistic. Simulation is conducted to compare the statistical powers of the Wald, the score, the generalized score and the likelihood...
متن کاملScore and Pseudo-Score Confidence Intervals for Categorical Data Analysis
This article reviews methods for constructing confidence intervals for analyzing categorical data. A considerable literature indicates that the method of inverting score tests performs well for a variety of cases. When the sample size is small or the parameter is near the parameter space boundary, this method usually performs much better than inverting Wald tests and sometimes better than inver...
متن کاملBartlett correction factors in logistic regression models
Bartlett correction factors for likelihood ratio tests of parameters in conditional and unconditional logistic regression models are calculated. The resulting tests are compared to the Wald, likelihood ratio, and score tests, and a test proposed by Moolgavkar and Venzon in Modern Statistical Methods in Chronic Disease Epidemiology, (Wiley, New York, 1986).
متن کاملLikelihood Ratio, Score, arid Wald Statistics in Models with Monotone Functions: Some Comparisons
BANERJEE AND WELLNER (2001) introduced and studied the likelihood ratio statistic for testing the hypothesis that a monotone function takes on a fixed value at a fixed point in the context of estimating the distribution function of the survival time in the interval censoring model. In this paper we continue to use the interval censoring model as a simple "test problem" . We introduce three natu...
