Analysis and Modelling of Survey and Other Data Containing Extra Zeros

We will develop and implement improved and more flexible methods for the analysis of data (including survey data) which contains extra zeros, through the use of semi-parametric models and models which incorporate dependence. The methods will impact on the practical analysis of data, enabling us to concentrate on the substantive problem of interest (rather than nuisance aspects of the models) and to draw valid conclusions from data containing extra zeros. The project will result in new statistical methods with associated software and quality research training.
