Source: Authors' analysis of determinants of the efficiency of national HIV/AIDS programs, based on the efficiency scores generated from the pooled DEA model. Notation: * p < 0.05, ** p < 0.01. Notes: The dependent variable is natural logarithm of efficiency scores from output-oriented DEA over years; coefficients for dummy variables on years 2003-2007 and the constant are suppressed for brevity; log refers to natural log; the total number of observations is 120. GNI denotes gross national income. The variance of the random error is estimated at 0.111. Additional file 1 (Table A5) provides the full model specification.
