# Causal Inference for Unobservable Multivariate Outcomes, with Applications to Brain Effective Connectivity

## Overview

Evaluating the causal effect of an intervention on multivariate outcomes is challenging when the outcomes are interdependent and derived rather than directly observed. Effective connectivity is one such derived relational outcome. We develop a causal inference framework combining potential outcomes with network-based structural equation modeling, identifying causal effects under partial interference.
