Relative-importance assessment of explanatory variables in generalized linear models: an entropy-based approach digital

by Claudio Giovanni Borroni, Nobuoki Eshima, Minoru Tabata

Year: 2016

The object of the present paper is to propose a method for relative-importance assessment of explanatory variables in generalized linear models, through an analysis of the variation of entropy of the response variable. First, the problem is reviewed in the ordinary regression model and some criteria to be met by a suitable measure are emphasized...

Gini’s cograduation index for the estimation of the coefficients of a quadratic regression model digital

by Claudio Giovanni Borroni

Year: 2006

Least square estimates of regression parameters may become unreliable when some outliers affect the data. This fact forces to search for different methods of estimation, some of which consist of substituting ranks to observations to avoid influences by extremes values.
