Hi Bala,

unfortunately I cannot tell about PIM, but I know that the user-written Stata command teradialbc allows bootstrapping.

Best regards

Ramon

Dominic Loske

unfortunately I cannot tell about PIM as well, but I provided an R code for a bootstrap with 1.000 replications following Simar and Wilson’s (1998) bias-correction of technical efficiency scores in input- and output-oriented DEA models.

Thank You Dominic and Ramon.
