  1. Estimating the effect of regression toward the mean under stochastic censoring.

    Article - En anglais

    This investigation estimated regression toward the mean in the evaluation of a blood cholesterol educational program in which the probability of return for a follow-up measure was positively related to the initial measure-a situation the authors term « stochastic censoring. » The situation in which selection is by a fixed cutpoint is well known.

    The authors estimate the extent of regression toward the mean when selection is probabilistically related to an initially higher blood cholesterol level.

    A Monte Carlo method is proposed, conditional on the observed data, for estimating the regression toward the mean and its precision.

    In 106 simulations, regression toward the mean was estimated to be 0.012 mmol/liter (standard deviation (SD), 0.032 mmol/liter).
