Data set used in some of OpenMx's examples, for instance WLS. The data were reported in Bollen (1989, p. 428, Table 9.4) This set includes data from 75 developing countries each assessed on four measures of democracy measured twice (1960 and 1965), and three measures of industrialization measured once (1960).
A data frame with 75 observations on the following 11 numeric variables.
Freedom of the press, 1960
Freedom of political opposition, 1960
Fairness of elections, 1960
Effectiveness of elected legislature, 1960
Freedom of the press, 1965
Freedom of political opposition, 1965
Fairness of elections, 1965
Effectiveness of elected legislature, 1965
GNP per capita, 1960
Energy consumption per capita, 1960
Percentage of labor force in industry, 1960
Variables y1-y4 and y5-y8 are typically used as indicators of the latent trait of “political democracy” in 1960 and 1965 respectively. x1-x3 are used as indicators of industrialization (1960).
