Bundled datasets (ergodic.datasets)
-----------------------------------

The package ships a small set of teaching datasets. We credit each source here
and state the terms it is published under.

- birthweight: maternal smoking and infant birthweight. From US natality records
  (public domain, National Center for Health Statistics), as used by Almond,
  Chay and Lee, "The Costs of Low Birth Weight", Quarterly Journal of Economics
  (2005), and Cattaneo, "Efficient Semiparametric Estimation of Multi-valued
  Treatment Effects", Journal of Econometrics (2010).

- pension401k: 401(k) eligibility and net financial assets. From the Survey of
  Income and Program Participation (public domain, US Census Bureau), as used by
  Chernozhukov, Chetverikov, Demirer, Duflo, Hansen, Newey and Robins,
  "Double/Debiased Machine Learning", Econometrics Journal (2018).

- smoking: California Proposition 99 and per-capita cigarette sales. Replication
  data published by the authors of Abadie, Diamond and Hainmueller, "Synthetic
  Control Methods for Comparative Case Studies", Journal of the American
  Statistical Association (2010), and widely redistributed with synthetic control
  software. The authors publish it without an explicit licence.

- germany: German reunification and GDP per capita. Replication data published
  by the authors of Abadie, Diamond and Hainmueller, "Comparative Politics and
  the Synthetic Control Method", American Journal of Political Science (2015),
  taken from the copy redistributed in the MIT-licensed pysyncon package. The
  authors publish it without an explicit licence.

- berkeley: UC Berkeley graduate admissions, 1973. The published aggregate table
  from Bickel, Hammel and O'Connell, "Sex Bias in Graduate Admissions: Data from
  Berkeley", Science (1975), stored as counts in the loader.

- asia, earthquake: small Bayesian networks. The structures and conditional
  tables are implemented from their source papers (Lauritzen and Spiegelhalter,
  "Local Computations with Probabilities on Graphical Structures", Journal of the
  Royal Statistical Society B, 1988; Pearl, "Probabilistic Reasoning in
  Intelligent Systems", 1988). The data are sampled from those networks, so they
  are the package's own.
