Generalized production function

Log-likelihood function for the generalized production function of Zellner and Revankar (1969)

zellner_revankar(
  theta,
  y,
  Z,
  sum = FALSE,
  gradient = TRUE,
  hessian = TRUE,
  repar = TRUE
)

`theta`	the vector of parameters
`y`	the vector of response
`Z`	the matrix of covariates
`sum`	if `FALSE`, a vector of individual contributions to the likelihood and the matrix of individual contributions to the gradient are returned, if `TRUE` a log-likelihood scalar and a gradient vector are returned
`gradient`	if `TRUE`, the gradient is returned as an attribute
`hessian`	if `TRUE`, the hessian is returned as an attrubute
`repar`	if `TRUE`, the likelihood is parametrized such that the constant return to scale hypothesis implies that two coefficients are 0
