Figure 3From: Differential mortality in Iran Scatter plot and fitted line of 45 q 15 against literacy (cubed) for females after censoring outlying data, Iran, 2004. Note: The scatter plot corresponds to those provinces in the a and b groups (provinces with plausible values of 45q15). While a linear fit is reasonable across the range of data values, an exponential or other non-linear form would better represent out of sample points.Back to article page
