From: Developing a comprehensive time series of GDP per capita for 210 countries from 1950 to 2015
GDP per capita estimates resulting from the final stage of the model for Somalia, in which a mixed effects model predicts out-of-sample data points for each country. Somalia was missing data after 2009, and this stage created predictions through 2015 based on year random effects and country-nested-in-region random effects. Bolded square data points indicate estimations made at this stage and starred data points indicate predictions from previous stages.
