Effects of outliers on mean, standard deviation and Pearson's correlation coefficient are well known. The Principal Components analysis uses Pearson's product moment correlation coefficients to construct composite indices from indicator variables and hence may be very sensitive to effects of...

This paper uses mixed combinatorial-cum-real particle swarm method to obtain a heuristically optimal order in which the constituent variables can be arranged so as to yield some generalized maximum entropy synthetic indicators that represent the constituent variables in the best...

The present study devises a computational scheme (and develops a FORTRAN 77 computer program) that may be appropriate to construct Pena’s DP2 (ordinal) synthetic indicator (Z ) from the partial indicators (X ) all of which are ordinal (ranking scores). An attempt has also been made to...
