Replication Data for Investigating Sequences in Ordinal Data: A New Approach with Adapted Evolutionary Models

It involves three complementary methodologies (frequency tables, transitional graphs, and dependency tables), as well as an established adaptation based on Bayesian dynamical systems, inferring a general system of change. The frequency tables count pairs of values in two variables and transitional graphs depict changes, showing which variable tends to attain high values first.

The dependency tables investigates which values of one variable are prerequisites for values in another, as a more direct test of causal hypotheses. We illustrate the proposed methods by analyzing the V-Dem dataset, and show that changes in electoral democracy are preceded by changes in freedom of expression and access to alternative information.
