Survival and growth curve analyses applied to a barnacle data set Freund, Vivien


A data set relating to the survival and growth of barnacles is examined. Survival distributions are compared by means of three nonparametric tests. The exponential model is then fitted for the survival distributions and a random effects model is developed for the slope. Polynomial growth curves are fitted and various hypotheses relating to the parameters are tested using firstly the model of Pothoff and Roy and secondly the model of Rao. Owing to the nature of the growth data, which is not longitudinal, this presents various statistical problems which are discussed.
