  • Iteration log likelihood (not concave) takes longer time to run xtfrontier for profit efficiency

    I was trying to run xtfrontier lnprofit lnpriceoflabor priceoffund lncostperloan lnnetloanportfo lnloanratio laborprice2 priceoffund2 lncostperloan2 lnnetloanportfo2 lnloanratio2 labornetport laborloanratio fundnetloanport fundloanratio loannetloanport loanloanratio t2 timelabor timefund timecostperloan timenetport timeloanratio, ti
    on STATA 14 to estimate profit efficiency.
    However, it is taking me too longer time to estimate the log likelihood outcomes as a result I could not get the estimated efficiency parameters for my profit function. How can I solve the problem? Thanks

      This topic also was posted in the General forum at

      https://www.statalist.org/forums/for...fit-efficiency

      where any response should be posted, since this Mata forum is used for discussions of Stata's Mata language, which is different than Stata's command language.
