Estimating equivalence scales and non-food needs in Egypt: Parametric and semiparametric regression modeling.

This paper investigated the appropriate specifications of Engel curves for non-food expenditure categories and estimated the deprivation indices of non-food needs in rural areas using a semi parametric examination of the presence of saturation points. The study used the extended partial linear model...
