Hi there,

I need some help in running a stochastic frontier analysis.

I am using the command "frontier", with output as the dependent variable, and a series of inputs to estimate the Cobb-Douglas production function, on a sample of 528 farms.

However, I get the following error message "initial values not feasible".

Could anyone suggest where the problem comes from?

Many thanks.

Georgeta
