Calculation of Entailed Rank Constraints in Partially Non-Linear and Cyclic Models
Peter L. Spirtes
The Trek Separation Theorem (Sullivant et al. 2010) states necessary and sufficient conditions for a linear directed acyclic graphical model to entail for all possible values of it…
Detecting Causal Relations in the Presence of Unmeasured Variables
Peter L. Spirtes
The presence of latent variables can greatly complicate inferences about causal relations between measured variables from statistical data. In many cases, the presence of latent va…
Causal Inference in the Presence of Latent Variables and Selection Bias
Peter L. Spirtes, Christopher Meek, Thomas S. Richardson
We show that there is a general, informative and reliable procedure for discovering causal relations when, for all the investigator knows, both latent variables and selection bias…
Directed Cyclic Graphical Representations of Feedback Models
Peter L. Spirtes
The use of directed acyclic graphs (DAGs) to represent conditional independence relations among random variables has proved fruitful in a variety of ways. Recursive structural equa…
Semi-Instrumental Variables: A Test for Instrument Admissibility
Tianjiao Chu, Richard Scheines, Peter L. Spirtes
In a causal graphical model, an instrument for a variable X and its effect Y is a random variable that is a cause of X and independent of all the causes of Y except X. (Pearl (1995…
