Effective Contingency Ranking Based on Composite Indices
Contingency ranking in power system transient stability is a complicated and time consuming task. To prevail over this difficulty, various indices are used. These indices are based on the concept of coherency and three dot products of the system variables. It is well known that some indices work better than others for a particular power system. This paper introduces an innovative composite seve...
متن کاملOn Construction of Robust Composite Indices by Linear Aggregation
weights to different indices, there are two approaches: the first in which the weights are determined on the basis of some information or considerations exogenous to the data on index variables ( ), X xkj ∈ and the second in which the weights are endogenously determined such that ). (X f w = The most robust composite index is the one that is exogenously determined since in that case w is used a...
متن کاملMultiplicative Zagreb Eccentricity Indices of Some Composite Graphs
Let G be a connected graph. The multiplicative Zagreb eccentricity indices of G are defined respectively as Π1(G) = ∏ v∈V (G) ε 2 G(v) and Π ∗ 2(G) = ∏ uv∈E(G) εG(u)εG(v), where εG(v) is the eccentricity of vertex v in graph G and εG(v) = (εG(v)) . In this paper, we present some bounds of the multiplicative Zagreb eccentricity indices of Cartesian product graphs by means of some invariants of t...
متن کاملA Statistical Analysis of Weights in Composite Qol Indices
Editor's Note: In a recent article published in Sociological Methods and Research, Michael Hagerty and Ken Land study the statistical foundations of how to construct composite or summary indices (e.g., Quality of Life indices) for a social unit (e.g., cities, states, nations) that will be endorsed by a majority of its citizens. Since this problem is of central importance to the Social Indicator...

subjectively or objectively by certain considerations extraneous to the dataset , X or alternatively they may endogenously be determined by the statistical information obtained from dataset X itself. Endogenous weights are frequently obtained by a statistical technique called the Principal Components Analysis (PCA), which maximizes the sum of squared coefficients of (the product moment) correla...
