Qtools tutorial

My article “Qtools: A Collection of Models and Tools for Quantile Inference” is available on the R Journal.


Quantile Regression course at ICSA 2016

A one-day short course in Quantile Regression (QR) will be presented on June 12 in Atlanta, GA.  This course will provide an introduction to principles of and methods for QR analysis. It will cover the basics as well as more advanced methods (models for discrete data, clustered data, transformation-based models for nonlinear and bounded responses).


The R package Qtools is now on CRAN! A tutorial is available here. See my Software page for more details.


lqmm 1.5.2

The new version of lqmm with bug fixes, amendments and new features is now on CRAN.

Identifying profiles of physical activity behaviours in the presence of non-ignorable missing data

Physical activity and inactivity are two independent dimensions over which children aggregate into distinct behavioural profiles. Read my new article ‘Probabilistic principal component analysis to identify profiles of physical activity behaviours in the presence of non-ignorable missing data’ in the Journal of the Royal Statistical Society: Series C at http://onlinelibrary.wiley.com/doi/10.1111/rssc.12105/abstract.
