Abstract [en]

This paper considers how measurement errors in the explanatory

variables affects the analysis of a Poisson regression model for frequencies

of recreational and shopping trips. Measurement errors can introduce

bias in the parameter estimates and the effects on this particular

data set and model is investigated. The structure of the data, with two

observations on each individual, makes it desirable to test for correlation

within individual. It is possible that tests of random effects are

sensitive to measurement error. The properties of tests of random individual

effects when there are measurement errors are therefore studied

in the paper. The results of a simulation study show that classical

measurement errors cause severe bias and Berkson measurement errors

produce little bias. The tests for random individual effects work

well both with measurement error and negatively correlated responses

according to the simulation study.
