  • Insignificant p-values for Stochastic Frontier Analysis (SFA)

    Hello,
    I have conducted an SFA, using the "sfcross"-command in Stata 17.0, as suggested by Belotti et al. (2012).
    My "Prob>chi2"-value of the overall model is significant at 1% but the p-values of the single parameters are either insignificant or even show no value at all (blank space).

    Any help is much appreciated.
    Thank you!
