a spatial weight matrix for spatial lag of the dependent variable
W_v
a spatial weight matrix for spatial lag of the symmetric error term
W_u
a spatial weight matrix for spatial lag of the inefficiency error term
inefficiency
sets the distribution for inefficiency error component. Possible values are 'half-normal' (for half-normal distribution) and 'truncated' (for truncated normal distribution).
By default set to 'half-normal'.
values
a vector of log likelihood function parameters
logging
an optional level of logging. Possible values are 'quiet','warn','info','debug'.
By default set to quiet.
costFrontier
is designed for selection of cost or production frontier
