Announcing the April meeting of the WA Branch of the Statistical Society of Australia. Our guest speaker is Dr John Henstridge, Managing Director of Data Analysis Australia.

Date: Tuesday, 9 April 2024.

Time: 6:00PM to 7:00PM (AWST)

Location: Cheryl Praeger Lecture Room, The University of Western Australia.


Models for Alcohol Effects: Liquor Outlets, Social Issues and Potential Harm

Whilst the harms caused by alcohol are often highly visible, the mechanism and detail of the effects is much less clear. Explorations of the effects are essentially statistical (or epidemiological) since harm is typically evidenced through increases in the level of health conditions or incidences of crime or misbehaviour. Once particular area of study is the effect of liquor outlets and whether they can be shown to affect the level of harm. Such studies have often been cited in legal cases, commonly in the context of an application for a new liquor licence.

Data Analysis Australia has reviewed many such studies, highlighting major statistical deficiencies in almost all. Recently we were asked to carry out our own such study to demonstrate how the methodology might be improved to overcome the many problems. This has involved a reasonably large dataset and a number of innovative steps in setting up a model, perhaps an order of magnitude more sophisticated than any previous study. The result demonstrates that better models are feasible and it throws more doubt upon the validity of previous studies. This work was done with a number of other Data Analysis Australia staff.
