Fig. 7: Plots of multivariate poverty indices for the dimension reduced model.
As expected, the curve behaves in a similar fashion to the cereals-only model of ref. 21 but also accounts for the increase in poverty observed around t = 1966 as seen in the alternative poverty index measures: the Head Count Index, Poverty Gap, and Squared Poverty Gap. These alternative measures have been scaled against the maximum of the index values. The model was constructed using data from 1959–1991 and verified against data in 2001 and 2005, each with more than 90% accuracy.
