Hello! Here's my #introduction:
I'm a Senior Researcher in #statistics at the University of Jyväskylä, Finland, where I currently run PREDLIFE project aiming to develop new methods and software for #Bayesian #CausalInference for complex #paneldata.

I'm broadly interested in Bayesian modeling, state space (hidden Markov) models, uncertainty #visualization, and statistical software development. I have developed several #rstats packages such as #KFAS, #bssm, #seqHMM, #walker and #dynamite.

New preprint and R package for causal inference and Bayesian modelling for complex panel data using Dynamic Multivariate Panel Models (DMPMs):
https://osf.io/preprints/socarxiv/mdwu5/
https://docs.ropensci.org/dynamite/index.html

DMPM supports
(1) joint modelling of multiple response variables from mixed distributions
(2) time-varying regression coefficients
(3) posterior predictive simulations for estimation of long-term causal effects
(4) Suitable for both large N and large T case as well as for univariate time series case (N=1)

We're looking for a senior researcher for CAUSALTIME project at the INVEST Research Flagship Centre at the University of Turku starting 1/2024 at the earliest.

The overall goal of the project is to develop new #Bayesian #causal inference methods for panel/time series data. Depending on your skills and interests, you can work on various methodological and/or applied social science research problems utilising the methods developed in the project.

My daughter and her friend googled me for a theme for her Father's Day card. So now they think I study space. I will enjoy being a cool space scientist instead of a statistician working on state space models.

I think I have at least a few years to find a collaborator for a paper related to actual space so she doesn't feel disappointed when she realizes the truth.

First time for me to review a double blinded paper where I'm sure both parties actually know each others identities (I've been on the other side before).
