    Clin Trials 9:293-302. 2012
    ..The requirement to examine the outcome at a prespecified sample size (SS) can be problematic, because the attained SS often differs from the planned SS...

    Biometrics 67:1321-9. 2011
    ..Comparisons of actual smoking status at one year with predictions from our model and from a variety of empirical methods suggest that our method gives excellent predictions...

    Biostatistics 14:340-50. 2013
    ..We derive the asymptotic distribution of the residuals and evaluate their performance by simulation in a range of parametric models. We apply our approach to data from a smoking cessation drug trial...
