Using Finite Mixture Modeling to Deal with Systematic Measurement Error: A Case Study
Min Liu, Gregory Robert Hancock, Jeffrey R. Harring · Journal of Modern Applied Statistical Methods · 2011
Conventional methods and analyses view measurement error as random. A scenario is presented where a variable was measured with systematic error. Mixture models with systematic parameter constraints were used to test hypotheses in the context of general linear models; this accommodated the heterogeneity arising due to systematic measurement error.
