Estimation of WASH-related mortality (deaths per thousand people per year)a.

Notes: *Significant at 90%, **Significant at 95%, ***Significant at 99%. Robust standard errors. The omitted region in these regressions is Sub-Saharan Africa (SSA); the omitted year is 2002.aA Breusch-Pagan specification test is highly significant (P-valuebHausman tests indicate that we cannot reject the hypothesis that the model estimates obtained from random effects and OLS (P-value = 0.99), and fixed effects and OLS (P-value = 0.38) specifications, are systematically different. The Hausman test however suggests that random effects and fixed effects estimates are different in the basic model (P-value = 0.0066) but not in the full model; also, see caveats in text.
