Poisson regression with a surrogate X:  an analysis of vitamin A and Indonesian children's mortality.
"A Poisson regression model with a surrogate X variable is proposed to help to assess the efficacy of vitamin A in reducing child mortality in Indonesia.  In a recent community trial, the mortality rate in villages receiving vitamin A supplementation was 35% less than in control villages.  However, at base-line, control villages were found to have slightly higher rates of xerophthalmia, an ocular disease caused by vitamin A deficiency.  It was therefore desirable to adjust the mortality comparison for base-line vitamin A levels as indicated by xerophthalmia prevalence.  This paper presents a parametric errors-in-X regression model developed for this purpose.  Likelihood methods for fitting and inference are discussed.  The model is illustrated on the Indonesian data set."
