Table 7. CHANNEL effect size calculations. Effect sizes are calculated as e^(d•C_{MWA}), where C_{MWA} = model weighted average coefficient, and d = real world difference. Appendix Table A8 presents the original workdays regression and a modified regression with an inequalityadjusted CHANNEL variable. Not surprisingly, the inequalityadjusted CHANNEL workdays regression results are very similar to the original results, suggesting that even when social and wealth inequalities influencing CHANNEL distribution are accounted for, being connected to the irrigation systems still matters.
