Our March newsletter features Data Analysis Australia’s response to the challenges of rapidly expanding “big data” sets, describing some recent applications and special statistical considerations. Our Analytical Idea illustrates the concept of cartograms, a type of map using distortion, to present information with a geographical component, with reference to the March 11 WA State election. We celebrate the achievement of 15 years at Data Analysis Australia for our Principal Managing Consultant Statistician, Anna Munday, highlight awards and recognition for a Director and a staff member, other staff movements and activities, and profile Dr Linda Eaton, Senior Managing Consultant Mathematician, who recently re-joined the company.
With several staff having attended the inaugural Longitudinal Data Conference in late October, our December newsletter has a focus on longitudinal surveys and other forms of longitudinal data. Our front page article discusses the value of longitudinal data collections and the potential for enhancing cross-sectional data by linking datasets to create a longitudinal dataset. Our Analytical Idea provides an introduction to analysing longitudinal data, with a particular focus on the use of sampling weights. We introduce several new and returning staff members, and profile Tamra Chapman, Managing Consultant Statistician, who joined us in September.
