Computes the sum of squares of error — gd_compute_fit

Measures the fit of the model to the data.

Usage

gd_compute_fit_lq(welfare, population, headcount, A, B, C, key_values)

welfare: numeric: Welfare vector (grouped).
population: numeric: Population vector (grouped).
headcount: numeric: Headcount index. Allows for vector.
A: numeric: Lorenz curve coefficient. Output of regres_lq()$coef[1].
B: numeric: Lorenz curve coefficient. Output of regres_lq()$coef[2].
C: numeric: Lorenz curve coefficient. Output of regres_lq()$coef[3].
key_values: named list: key values for lq fit, calculated using A, B, C parameters using gd_lq_key_values
