L_hnv: SFA half-normal log likelihood function

In ssfa: Spatial Stochastic Frontier Analysis

SFA half-normal log likelihood function

Description

This function is used to estimate the parameters of the classical SFA model where half-normal distribution of inefficiency term is assumed.

Usage

L_hNV(p, y = y, X = X, sc = sc)

Arguments

p	a vector with the parameters to be estimated.
y	the dependent variable.
X	the model matrix.
sc	specifies the form of the frontier model (-1 = cost, 1 = production).

Value

Value of the SFA log likelihood function.
