causaleffect: an R package for causal effect effect identification

Functions for identification and transportation of causal effects. Provides a conditional causal effect identification algorithm (IDC) by Shpitser, I. and Pearl, J. (2006) http://ftp.cs.ucla.edu/pub/stat_ser/r329-uai.pdf, an algorithm for transportability from multiple domains with limited experiments by Bareinboim, E. and Pearl, J. (2014) http://ftp.cs.ucla.edu/pub/stat_ser/r443.pdf and a selection bias recovery algorithm by Bareinboim, E. and Tian, J. (2015) http://ftp.cs.ucla.edu/pub/stat_ser/r445.pdf. All of the previously mentioned algorithms are based on a causal effect identification algorithm by Tian , J. (2002) http://ftp.cs.ucla.edu/pub/stat_ser/r309.pdf.

Recent changes (for all changes, see NEWS file).

Changes from version 1.3.12 to 1.3.13

• Fixed an incorrect graph definition in the IDC algorithm.

Changes from version 1.3.11 to 1.3.12

• The package no longer depends on the 'ggm' package.
• The package no longer requires the 'XML' package, now suggests instead.

Changes from version 1.3.10 to 1.3.11

• Fixed inconsistency with function arguments when computing causal effects with surrogate experiments using 'aux.effect'.
• Fixed a rare issue with simplification.

Changes from version 1.3.9 to 1.3.10

• Fixed a bug with simplification.

Changes from version 1.3.8 to 1.3.9

• Added a new parameter 'stop_on_nonid' to all identifiability algorithms. Value 'TRUE' mimics old functionality, where an error is produced when a non-identifiable effect is discovered. Value 'FALSE' continues the recursion.
• Fixed a bug in the recoverability algorithm.
• Fixed a bug in the transportability algorithm.
• Fixed a bug related to identification using surrogate outcomes.

Changes from version 1.3.7 to 1.3.8

• Added a new function 'surrogate.outcome' to compute causal effects using surrogate outcomes.

Changes from version 1.3.6 to 1.3.7

• Fixed an issue with simplification introduced in version 1.3.6.
