Table 3 Results of regression for printed materials

From: Enhancing the comparability of costing methods: cross-country variability in the prices of non-traded inputs to health programmes

Number of observations = 35
  Adjusted r2 = 0.5446 F statistic = 21.33 P of F statistic < 0.0001
Variable Coefficient SE T P
ln GDP per capita -.9194 0.1835 -5.01 0.000
Flyer cost (dummy) -1.558 0.3767 -4.13 0.000
Constant -.2874 1.623 -0.18 0.861
  1. Dependent variable: log ratio of price of printed materials to GDP per capita
  2. Breusch-Pagan test of heteroskedasticity: 1.02 (p = 0.31 (Chi2)).
  3. VIF test for multicolinearity:1.02 (less than 2 indicates no multicollinearity)
