Pseudolikelihood estimator of the λ parameter
1 | fan(lambda_fan, resp, Ey, ineffD)
|
lambda_fan |
the λ=σ_u/σ_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 |
