A Monte Carlo comparison of three consistent bootstrap procedures
(Taylor & Francis, 2009-04)
Since bootstrap samples are simple random samples with replacement from the original sample, the information content of some bootstrap samples can be very low. To avoid this fact, some authors have proposed several variants ...

Multivariate explanatory model for sporadic carcinoma of the colon in Dukes’ stages I and IIa
(Ivyspring International Publisher, 2009)
We obtained before an explanatory model with six dependant variables: age of the patient, total cholesterol (TC), HDL cholesterol (HDL-C), VLDL cholesterol (VLDL-C), alkaline phosphatase (AP) and the CA 19.9 tumour marker. ...

A generalized model of equality measures in network location problems
(Elsevier, 2008-03)
In this paper, the concept of the ordered weighted averaging operator is applied to define a model which unifies and generalizes several inequality measures. For a location x, the value of the new objective function is the ...

Reduced bootstrap for the median
(Academia Sinica (Institute of Statistical Science), 2004-10)
In this paper we study a modified bootstrap that consists of only considering those bootstrap samples satisfying k1 ≤ νn ≤ k2, for some 1 ≤ k1 ≤ k2 ≤ n, where νn is the number of distinct original observations in the ...

Continuous location problems and Big Triangle Small Triangle: constructing better bounds
(Springer, 2009-11)
The Big Triangle Small Triangle method has shown to be a powerful global optimization procedure to address continuous location problems. In the paper published in J. Global Optim. (37:305–319, 2007), Drezner proposes a ...
