Estimation of an Almost-Ideal Demand System

Description

Estimation of an Almost-Ideal Demand System using nlsur().

Usage

ai(w, p, x, z, a0 = 0, data, scale = FALSE, logp = TRUE, logexp = TRUE, ...)

Arguments

w	character vector of m budgetshares used for estimation.
p	character vector of m prices.
x	single character vector of total expenditure.
z	character vector of k demographic variables.
a0	start value for translog price index.
data	data.frame containing the variables.
scale	logical if TRUE Rays (1983) scaling is used.
logp	logical if prices are log prices.
logexp	logical if expenditure is log expenditure.
...	additional options passed to nlsur
