fan: Pseudolikelihood estimator of the lambda parameter

In semsfa: Semiparametric Estimation of Stochastic Frontier Models

Pseudolikelihood estimator of the \lambda parameter

Description

Pseudolikelihood estimator of the \lambda parameter

Usage

fan(lambda_fan, resp, Ey, ineffD)

Arguments

lambda_fan	the \lambda=\sigma_u/\sigma_v parameter to be estimated
resp	the single response variable Y observed
Ey	the conditional expectation estimate obtained in the first step of the algorithm
ineffD	logical: TRUE for estimating a production function, FALSE for estimating a cost function; this is done for usage compatibility with frontier package

Value

Estimated \lambda parameter

Note

Internal usage only
