But imperfect competition and other operating constraints force the DMUs to operate in a variable returns to scale. Banker et al. (1984) proposed a variable returns to scale (VRS) model. Both output-orientated and input-orientated models are very similar dual problems. The generic input-orientated model is as follows: min h À e m X sÀ i þ s X i¼1 n X j¼1 n X j¼1 n X ! srþ r¼1 kj xij þ sÀ i ¼ h xij0 i ¼ 1; 2; . ; m ð4:1Þ kj yrj À kj ¼ 1 srþ ¼ yrj0 kj ! 0 r ¼ 1; 2; . ; s j ¼ 1; 2; . ; n j¼1 where DMUjo represents one of the n DMUs under evaluation, and xijo and yrjo are the ith input and rth output for DMUo, respectively, and si− and sr+ represent the ith input and rth output slacks.
Finally, two robustness checks have been performed for the proposed model: First, the model is developed for the development sample and the results have been validated for the validation sample. Second, an out of sample validation for all the accounts opened between January 1998 and December 2000 has been performed. 4. The sample size used in the estimation is 52,843. 99 % level. 75. 0001 provided due to the conﬁdentiality 40 3 Double Hurdle Model: Not if, but When Will Customer Attrite? on the explanatory variables, numbers of installment, limit, prime rate, interest rate, value of the goods bought and product types seem to influence the ﬁrst hurdle.
0 where 1 /\1; and / À 1 is the proportional increase in outputs that could be achieved by the ith DMU, with input quantities held constant. N1 is an N Â 1 vector of ones. This convexity constraint N10 k ¼ 1 represents the scale; if it is included, then the model assumes variable returns to scale (VRS). 4 4 Optimizing the Media Mix … Estimation There is no standard routine available in SAS to estimate this DEA model. There are plenty of freeware available in the Internet to do this DEA estimation.
