In a new preprint, we study causal effect identification with multiple data sources. We show that certain clustering and pruning operations of the causal graph are identification invariant. This means that we may use the smaller graph to make conclusions on the larger graph.

Santtu Tikka and I wrote two preprints on identification in missing data problems. The results have interesting implications for multiple imputation.

Multiple imputation and full law identifiability, arxiv.org/abs/2410.18688

Forestry is important for the economies of Finland and Sweden and provides interesting problems also for statisticians. In a recent work done in collaboration with Skogforsk, we optimized the inventory decisions in operational forestry. doi.org/10.1093/biom...

Simulating values from a known distribution is a basic task in statistics. But how to simulate from a counterfactual distribution? We consider this question in a recently published paper.
