ci_bod_constr_bad {Compind} | R Documentation |
The constrained Benefit of the Doubt function introduces additional constraints to the weight variation in the optimization procedure (Constrained Virtual Weights Restriction) allowing to restrict the importance attached to a single indicator expressed in percentage terms, ranging between a lower and an upper bound (VWR); this function, furthermore, allows to calculate the composite indicator simultaneously in presence of undesirable (bad) and desirable (good) indicators allowing to impose a preference structure (ordVWR).
ci_bod_constr_bad(x, indic_col, ngood=1, nbad=1, low_w=0, pref=NULL)
x |
A data.frame containing simple indicators; the order is important: first columns must contain the desirable indicators, while second ones the undesirable indicators. |
indic_col |
A numeric list indicating the positions of the simple indicators. |
ngood |
The number of desirable outputs; it has to be greater than 0. |
nbad |
The number of undesirable outputs; it has to be greater than 0. |
low_w |
Importance weights lower bound. |
pref |
The preference vector among indicators; For example if |
An object of class "CI". This is a list containing the following elements:
ci_bod_constr_bad_est |
Composite indicator estimated values. |
ci_method |
Method used; for this function ci_method="bod_constr_bad". |
ci_bod_constr_bad_weights |
Raw weights assigned to each simple indicator. |
ci_bod_constr_bad_target |
Indicator target values. |
