Dear statisticians!
This is a kind reminder of that the Oslo section of the Norwegian Statistical Association (Norsk Statistisk Forening) organizes a Statistics evening with a very actual presentation by Geir Storvik, Professor in Statistics, UiO, on how Sequential Monte Carlo for Covid-19 is used in Norway.
For those registered, we shall also have free sushi, pizza, beverages and a great social gathering with your fellow statisticians. Others are still very welcome on zoom. Also, please, send me an email if you haven't registered but want to attend physically.
Date: 11. May, 2022
Time: from 17:00. Food and beverages will be served from 17.00. The presentation will start around 17.15, and we will finish off around 18.30.
Food and beverages: Sushi, Pizza, soda.
Format: Hybrid, see also https://sites.google.com/site/nsfavdoslo/home/temakveld-v%C3%A5r-2022
Place: Norsk Regnesentral Gaustadalleen 23a, room Alfa Omega. and Zoom https://uio.zoom.us/j/64331482931?pwd=bUkySWtiU2tkUWlwQ2dPMjU2U1RWQT09

Title: Sequential Monte-Carlo for COVID-19 modelling
Abstract:
The Covid-19 pandemic has required most countries to implement complex sequences of non-pharmaceutical interventions, with the aim of controlling the transmission of the virus in the population. To be able to take rapid decisions, a detailed understanding of the current situation is necessary. Estimates of time-varying, instantaneous reproduction numbers represent a way to quantify the viral transmission in real time. They are often defined through a mathematical compartmental model of the epidemic, like a stochastic SEIR model, whose parameters must be estimated from multiple time series of epidemiological data. Because of very high dimensional parameter spaces (partly due to the stochasticity in the spread models) and incomplete and delayed data, inference is very challenging. We propose a state space formalisation of the model and a sequential Monte Carlo approach which allow to estimate a daily-varying reproduction number for the Covid-19 epidemic in Norway with sufficient precision, on the basis of daily hospitalisation and positive test incidences. The method was in regular use in Norway during the pandemics and appears to be a powerful instrument for epidemic monitoring and management.
We hope to see many of you there!
