Simulating counterfactuals

1 code implementation27 Jun 2023 Juha Karvanen, Santtu Tikka, Matti Vihola

Counterfactual inference considers a hypothetical intervention in a parallel world that shares some evidence with the factual world.

Generalizing experimental findings: identification beyond adjustments

no code implementations14 Jun 2022 Juha Karvanen

We aim to generalize the results of a randomized controlled trial (RCT) to a target population with the help of some observational data.

Clustering and Structural Robustness in Causal Diagrams

1 code implementation8 Nov 2021 Santtu Tikka, Jouni Helske, Juha Karvanen

Graphs are commonly used to represent and visualize causal relations.

Estimation of causal effects with small data in the presence of trapdoor variables

1 code implementation6 Mar 2020 Jouni Helske, Santtu Tikka, Juha Karvanen

This bias is related to variables that we call trapdoor variables.

Causal Effect Identification from Multiple Incomplete Data Sources: A General Search-based Approach

no code implementations4 Feb 2019 Santtu Tikka, Antti Hyttinen, Juha Karvanen

Causal effect identification considers whether an interventional probability distribution can be uniquely determined without parametric assumptions from measured source distributions and structural knowledge on the generating system.

Enhancing Identification of Causal Effects by Pruning

no code implementations19 Jun 2018 Santtu Tikka, Juha Karvanen

Causal models communicate our assumptions about causes and effects in real-world phe- nomena.

Simplifying Probabilistic Expressions in Causal Inference

no code implementations19 Jun 2018 Santtu Tikka, Juha Karvanen

Obtaining a non-parametric expression for an interventional distribution is one of the most fundamental tasks in causal inference.

Causal Inference

Surrogate Outcomes and Transportability

no code implementations19 Jun 2018 Santtu Tikka, Juha Karvanen

Identification of causal effects is one of the most fundamental tasks of causal inference.

Causal Inference

Estimating complex causal effects from incomplete observational data

no code implementations5 Mar 2014 Juha Karvanen

Despite the major advances taken in causal modeling, causality is still an unfamiliar topic for many statisticians.

Additive models Imputation

Study design in causal models

no code implementations13 Nov 2012 Juha Karvanen

The causal assumptions, the study design and the data are the elements required for scientific inference in empirical research.
