  • DEA commands: dea vs. teradialbc

    Good day,

    Using the dea command produces technical efficiency scores with values b/t 0-1. However, I understand these are not bias corrected. Thus, I am using the teradialbc command to estimate bias-corrected scores with confidence limits. However, the technical efficiency and bias-corrected technical efficiency results generated by this command have values b/t 1-3.5. Is there any way to convert these values to standard 0-1 efficiency scores or is this not correct/appropriate? The "te1" var which is generated by teradialbc is labeled "Farrel based TE measure under CRS" which is the same specification I use for the dea command. Thanks in advance, Robert

    Hi, Robert, I also had the same problem but someone had suggested to convert it by dividing "1" by the TE scores, for example : 1/1.35 = 0.7407 . Hope it helps
