SSA Canberra Branch Meetings

  • The Annual General Meeting of the SSA Canberra Branch will be held in hybrid format, both in person at a room at ANU (to be advised) and by zoom, at 5.00pm Tuesday 26 March 2024. The agenda is available at the Google Drive SSA Canberra Branch AGM documents, which includes the details for joining the meeting via Zoom. If you cannot attend you can appoint a proxy; the form is also available at the Google Drive link above. The quorum for AGMs is 15, so please make an effort to attend in-person or on zoom so we make sure we achieve that number.

    An important part of the AGM is to elect a new Council for 2024-2025. If you are interested in joining Council the nomination form is available at the Google Drive link above. Please contact me if you want to discuss what that involves.

    At this meeting we will also be considering two important issues for the Branch. Firstly, following a survey of members in February there were two proposed new names for the Branch that had equal support. At the AGM we will be determining which of these will be the new name. Secondly, the present rules relating to filling vacancies in President and President-Elect have some inconsistencies and we are proposing amendments that clarify procedures in all circumstances.

    All members will have the opportunity to vote for the new branch name and rule changes. For members not attending the meeting in person, votes may be cast by either

  • (a)  attending via zoom and communicating votes by 1 to 1 message within zoom to a nominated Council member – more details in a later notice, or
  • (b)  appointing someone at the meeting as a proxy and, if desired, directing that proxy how to vote on your behalf – details in the proxy form.

Other documents relating to the AGM will be added to the attached documents on the Google Drive SSA Canberra Branch AGM documents over the next two weeks.

After the AGM there will be a talk, starting at 6.00pm, given by Pauline Ding, the outgoing branch president.

Details of the talk and its zoom link are given below. The AGM is on a separate zoom link, given with the attached agenda.

Topic: Optimising Twin Uniform Distribution for Multiplicative Noise Data Masking


Multiplicative noise masking is a well-known method to perturb data for privacy protection purpose. Twin uniform distribution has been introduced in the literature as a distribution for multiplicative noise, given the simplicity in its mathematical form and the ability to provide good value protection without sacrificing statistical utility. We further explore the impact of various distribution parameters on the performances of privacy protection and utility loss when multiplying twin uniform noise for data masking. An approach to optimise the multiplicative noise scheme with twin unform noise distribution is proposed. We apply the optimisation algorithm to a real accounts payable dataset, and conclude that it yields good results for both privacy and utility.


Pauline is a lecturer in Statistics in the University of Wollongong, Australia. Before that, she had worked as statistical consultant in the Australian National University. Her recent research interests are the area of data privacy.

Dinner: After the talk we will be holding a dinner at The Golden Drum restaurant, Shop 1/14 Childers St, Canberra. (Golden Drum | Canberra ACT | Facebook). If you are interested in attending the dinner, please let me know by 5pm Monday 25 March by entering your details at SSA Canberra Branch dinner attendance sheet or contacting me (; 0407 916 868). Please regard this as a firm commitment, not just an intention. For withdrawals after the deadline, please remove your name from the sheet and phone or text me (0407 916 868).

NOTE: We are offering discounts to SSA Early Career and Student members who attend dinner! Specifically, dinners will be a fixed charge of $10 for student members and $20 for early career members.
