Gordon Anderson, "Making Inferences About the Polarization, Welfare and Poverty of Nations: A Study of 101 Countries 1970-1995", Journal of Applied Econometrics, Vol. 19, No. 5, 2004, pp. 537-550. The Data are contained in the file AEDATF.TXT in a 101 x 8 matrix with columns 1 3 5 7 containing the natural log of per capita gnp at constant $us, and columns 2 4 6 8 containing the population weights for the corresponding years 1970 1978 1987 and 1995. Each row of the matrix takes two rows in the file. All data are drawn from the World Bank Development Indicators Disc for the year 2000. This file, which is an ASCII file in DOS format, is zipped in the file anderson-data.zip. The polarization tests are contained in Gauss files pol1.g through pol4.g, and the stochastic dominance tests are contained in Gauss files sd1.g through sd4.g. All these files, which are ASCII files in DOS format, are zipped in the file anderson-progs.zip. The four file numbers for each class of program correspond to: 1. independent unweighted comparisons 2. dependent unweighted comparisons 3. independent weighted comparisons 4. dependent weighted comparisons.
