tpcExample

A small simulated data example intended to showcase the TPC algorithm. Note that the variable name
prefixes defines with period they are related to ("child", "youth" or "oldage").

datasets

Various tools for inferring causal models from observational data. The package
includes an implementation of the temporal Peter-Clark (TPC) algorithm. Petersen, Osler
and Ekstrøm (2021) <doi:10.1093/aje/kwab087>. It also includes general tools
for evaluating differences in adjacency matrices, which can be used for evaluating
performance of causal discovery procedures.
