UNICEF Technical Note n°185 (2007): How to calculate Average Annual Rate of Reduction (AARR) of Underweight Prevalence

Special Note: there seem to be a missing data point in the example provided. The example to generate the AARR seems to be based on 8 data points (including 2005) while the table provides only 7 data points. When using the 7 data points, the coefficient equals -0.0669 (and not -0.06613) and AARR is still 6.4%.
