Excerpt from Funny Stats Competition Announcement

What’s the funniest thing that’s ever happened to you during your statistical career? Or the funniest thing that a student or colleague has said to you? The Queensland Branch of the Statistical Society of Australia is gathering funny statistical stories for their Christmas party. The best story, as voted by our members on the night of the party, will win a 200 dollar (AUD) Amazon voucher. We will post the funniest entries on this web site.

There’s no geographical limit, so please write in from anywhere. Anonymous entries are welcome, but contact details must at least be provided to be awarded the prize. Any format is acceptable, so it could be a picture, a recording of you regaling your story, anything at all. Send your stories/pictures/recordings to Adrian: a.barnett@qut.edu.au. Entries close 20 November, or present live on the night.

Here are some examples:

* POSTGRADUATE STATS STUDENT: “I’ve opened the dataset for the first assignment, but it’s just numbers.”
* REVIEW FROM THE AJE: “I’m no expert in Baynesian statistics.”
* At a Valencia meeting a friend stuck a sticker on David Spiegelhalter’s back that read: “I’M A FREQUENTIST”

Time: 2:30pm – 3:30pm

OESR offices, city, details soon

Speakers:

* Harvey Goldstein. Professor of Social Statistics, Centre for Multilevel Modelling at the University of Bristol. Speaking on the UK Literacy Report.
* Australian Bureau of Statistics. Upcoming Census.
* Helen MacGillivray. Professor of Mathematical Sciences, Queensland University of Technology. IASE.

SSAI ANNUAL GENERAL MEETING

The Qld Branch AGM will be held at 5pm, ABS, Training Room 1 (3R 159), Level 3, 639 Wickham St, Fortitude Valley (1).

ORDINARY BRANCH MEETING: Tuesday 9 March, 2010

Following the AGM there will be a Branch meeting addressed by Dr Martin Wolkewitz.

SPEAKER: Dr Martin Wolkewitz, University of Freiburg

TITLE: Understanding and avoiding survival bias: An application of multistate models in a cohort of Oscar nominees.

TIME: 4.30pm – 6pm

VENUE: ABS, Training Room 1 (3R 159), Level 3, 639 Wickham St, Fortitude Valley1.

DINNER: Members and guests are invited to join the speaker at a nearby restaurant.

ABSTRACT:

Survival bias is a common concern in applications of survival analysis. The reason is often related to sampling schemes or time-dependent intermediate events. In many situations the bias can be avoided by a proper statistical analysis. Multistate models provide a relevant framework to display and circumvent certain types of survival bias. In this talk I recall techniques which are available and implemented in statistical softwares to avoid these types of bias. Using Lexis diagrams I illustrate length bias as well as time-dependent bias which occurred jointly in a study of Academy Award-winning actors and actresses. Several historical as well very recent applications in epidemiological fields are discussed.

BIOGRAPHY:

Dr Wolkewitz has a Diploma in Mathematics and a Ph.D. in Epidemiology. He is currently a senior statistician with a specific expertise in the application of event-history analysis and multistate modelling methodology to data arising in the field of health care epidemiology. Dr Wolkewitz joinrf the Research Unit FOR 534 “Statistical modeling and data analysis in clinical epidemiology” which is funded by Deutsche Forschungsgemeinschaft (DFG).

The Other Measurement Error Problem

Aurore Delaigle

Department of Mathematics and Statistics, University of Melbourne

 

In many real life applications, observations can not be measured precisely and the only data available are contaminated by measurement errors (for example, due to the inaccuracy of the measurement device used). When applied to such data, standard regression estimators are not consistent. A lot of attention in the literature has been devoted to the development of techniques for regression estimation which are valid in the error case, and we will discuss a recent nonparametric solution to this problem. Another important problem which has been much less studied in the measurement error literature is the estimation of the “variance curve” in regression. We will show that the two problems are strongly related, and present some techniques for estimating the variance curve. Aurore is a Principal Research Fellow/QEII Fellow in the Department of Mathematics and Statistics at the University of Melbourne. She completed her PhD at the Institute of Statistics, Université Catholique de Louvain in Belgium. She is currently on leave from her position as Associate Professor at the University of Bristol. She is an associate editor for the Journal of the American Statistical Association, the Journal of Computational and Graphical Statistics, Statistica Sinica and the Journal of the Korean Statistical Society. Aurore’s research interests include nonparametric curve estimation, measurement error, bandwidth selection and functional data analysis.

The seminar will be followed by refreshments in the Mathematics tea room (67-704).
