ci_rbod {Compind} | R Documentation |
Robust Benefit of the Doubt approach (RBoD) is the robust version of the BoD method. It is based on the concept of the expected minimum input function of order-m so "in place of looking for the lower boundary of the support of F, as was typically the case for the full-frontier (DEA or FDH), the order-m efficiency score can be viewed as the expectation of the maximal score, when compared to m units randomly drawn from the population of units presenting a greater level of simple indicators", Daraio and Simar (2005).
ci_rbod(x,indic_col,M,B)
x |
A data.frame containing score of the simple indicators. |
indic_col |
Simple indicators column number. |
M |
The number of elements in each of the bootstrapped samples. |
B |
The number of bootstrap replicates. |
An object of class "CI". This is a list containing the following elements:
ci_rbod_est |
Composite indicator estimated values. |
ci_method |
