Notes: ¹Indicates the number of households reporting the event. ²Placed in [..] is the percentage of households reporting CHE. ³Placed in (..) is the standard deviation. ⁴Placed in {..} is the mean of the stated row variable.
Models 1 is based on the Xu [1] procedure described in the text with varying level of household scale multiplier. *Model 1A uses household scale multiplier β = 0.41, and 45^th – 55^th percentile to compute subsistence expenditure. Model 1B household scale multiplier β = 0.56, and 45^th – 55^th percentile to compute subsistence expenditure.
