- Meta-analysis, funnel plots and sensitivity analysisJ Copas

Department of Statistics, University of Warwick, Coventry CV4 7AL, UK*Biostatistics*1:247-62. 2000..Correcting for this bias is not possible without making untestable assumptions. In this paper, a sensitivity analysis is suggested which is based on fitting a model to the funnel plot. Some examples are discussed... - Using regression models for prediction: shrinkage and regression to the meanJ B Copas

Department of Statistics, University of Warwick, Coventry, UK*Stat Methods Med Res*6:167-83. 1997..Shrinkage is a particularly serious problem if the sample size is small and/or the number of covariates is large. Shrinkage of predictors is illustrated by two examples. A more general formulation is suggested... - Reanalysis of epidemiological evidence on lung cancer and passive smokingJ B Copas

Department of Statistics, University of Warwick, Coventry CV4 7AL*BMJ*320:417-8. 2000..To assess the epidemiological evidence for an increase in the risk of lung cancer resulting from exposure to environmental tobacco smoke... - A sensitivity analysis for publication bias in systematic reviewsJ B Copas

Department of Statistics, University of Warwick, Coventry, UK*Stat Methods Med Res*10:251-65. 2001..Publication bias leads to lower values, and greater uncertainty, in treatment effect estimates. Two examples are discussed. An appendix lists the S-plus code needed for carrying out the analysis...
