100 year jubilee of the Finnish Statistical Society June 8-9 2023 in Helsinki

Dear members of the Finnish Statistical Society and other friends of statistics,

The Society celebrated its honourable centenary in 2020. The coronavirus epidemic prevented the celebration of the anniversary in 2020 and after. We are celebrating the wonderful history of the Society at the 100+ anniversary celebration in Helsinki on June 8-9, 2023. The event location is Porthania of the University of Helsinki, Yliopistonkatu 3. Register for the anniversary using the registration form (link) and by paying the participation fee (payment instructions below).

The main speakers of the anniversary celebration are Deborah Ashby (Imperial College, President of the Royal Statistical Society 2019–2020) and Jouni Kuha (London School of Economics and Political Science). Due to the jubilee year, the topics of the presentations include not only current research and the new online statistical dictionary (to be published shortly by the Society), but also the history of the Society and the history of statistics in Finland.

The presentations on both mornings will be held in English, whereas the afternoons are in Finnish. Participants will receive a copy of the Statistical Dictionary when they arrive on June 8th, as long as there are still copies left at that time.

The Society offers coffee and tea on both days. Participants pay for their own lunch. On the first evening, 8th of June, a gala dinner is organized. Dinner is included in the participation fee.

Poster competition

A poster competition will be organized as a part of the event. The topic of the poster can be theoretical or applied. The best poster is chosen by public vote. In addition to the honour of winning, the winner receives a cash prize and a discount voucher for books of Wiley. You can register for the poster competition at the same time you register for the anniversary. You can also register for the poster competition by e-mailing the secretary (sihteeri@tilastoseura.fi) before the 15th of May.

Registration and payment instructions

The participation fee is 80 euros for members and 130 euros for others if you sign up before the 15th of March (early bird price). After that, the registration fee is 100 euros for members and 150 euros for others. For students and graduate students, the participation fee is 0 euros, which does not entitle to participate in the dinner, or 80 euros with dinner. Payments should be made to the account
