This volume contains contributions presented at the XVIII Annual Congress of the Portuguese Statistical Society. It presents new models for specific topical problems and will be a valuable resource for all those working in modeling statistical data.

Statistics has been a main tool in almost every field of activity and an essential part of applied scientific work, supporting conclusions and offering insights into new uses for established methodologies, thus making it a valuable resource in looking for faceless facts. Model construction describing populations or phenomena subject to randomness use a wide range of methods. Data collection provides the basis for modelling and assumption verification. Modelling must be conducted using suitable techniques that give researchers the means to search for hidden facts or behaviours. This may be addressed by fitting pre-defined shapes and distributions to the data or by allowing the data to reveal its intrinsic properties by using nonparametric methods. This volume contains a selection of contributions presented at the XVIII Annual Congress of the Portuguese Statistical Society.

Application of methodologies and modeling to describe random phenomena A valuable resource for all those working in modeling statistical data New models are proposed for specific topical problems Includes supplementary material: sn.pub/extras
