This page provides some files for the analysis of the hierarchical linear models in “Causal Hetereogeneity in Comparative Research: A Bayesian Hierarchical Modelling Approach.” American Journal of Political Science 42:1233-1259 (1998).

• The BUGS file fitting the hierarchical linear model. Note that macro predictors in this file are read in the following order: (1) OECD demand, (2) OECD Exports, (3) OECD Imports, (4) Leftist Government, and (5) Lagged Growth. This order differs from that reported in the paper at Table 2.
• Alvarez, Garrett and Lange data formatted for BUGS
• Initial values

An interesting elaboration of the model involves drawing the random effects from a t distribution, instead of a normal. If there are outliers among the random effects, the t distribution will provide a robust estimate of the effects of the macro predictors:
