Installation After downloading, gunzip the file and untar (using tar xvf StochFrontier.tar). Typing install.sh should compile all code and create the executable mixSFDP2 in the StochFrontier directory. The code assumes availability of gcc and g++. It may be possible to replace them with different C and C++ compliers. Deficiencies In the case of the varying efficiency distribution model, the current implementation ONLY works for an exponential centring distribution (i.e. j = 1). This limitation should be solved fairly soon.
