Structural Equation Modeling. 2009 Apr 15;16(2):382-90. DOI: 10.1080/107055109027513821070-5511http://hdl.handle.net/10230/46123A typical structural equation model is intended to reproduce the means, variances, and correlations or covariances among a set of variables based on parameter estimates of a highly restricted model. It is not widely appreciated that the sample statistics being modeled can be quite sensitive to outliers and influential observations, leading to bias in model parameter estimates. A classic public epidemiological data set on the relation between cigarette purchases and rates of 4 types of cancer among states in the United States is studied with case-weighting methods that reduce the influence of a few cases on the overall results. The results support and extend the original conclusions; the standardized effect of smoking on a factor underlying deaths from bladder and lung cancer is .79.application/pdfeng© This is an Accepted Manuscript of an article published by Taylor & Francis in Structural Equation Modeling on 2009 Apr 15, available online: http://www.tandfonline.com/10.1080/10705510902751382info:eu-repo/semantics/articlehttp://dx.doi.org/10.1080/10705510902751382info:eu-repo/semantics/openAccess
