In this thesis, we will study issues related to prediction problems. In particular, we consider the prediction of recurrent events. For this, we develop different prediction models when these events can be modeled using homogeneous or nonhomogeneous Poisson processes. Amongst these models, we are interested in those using random effects because they possess interesting features. We propose a predictive model using empirical Bayes techniques and the maximum entropy principle in order to model the random effects for the unknown parameters. We will show that for the prediction of recurrent events, our first model using as a prior the two moments maximum entropy distribution, which is equivalent to the truncated normal distribution, compared very favorably to the negative binomial model that uses as a prior the gamma distribution. We also present an extension of the approach developed in our first model: because of the two moment condition on our maximum entropy priors, we were restricted to considering only cases where the coefficient of variation was less than or equal to 1. We remove this restriction by the use of higher moment maximum entropy priors in the prediction of recurrent events using homogeneous and nonhomogeneous Poisson processes. We assess the performance of such models through extensive simulation studies and some real data sets.
