Response surface designs using the generalized variance inflation factors
(Cogent OA, 2015)
We study response surface designs using the generalized variance inflation factors for subsets as an extension of the variance inflation factors.
Revisiting some design criteria
(Athens Institute for Education and Research, 2015)
We address the problem that the A (trace) design criterion is not scale invariant and often is in disagreement with the D (determinant) design criterion. We consider the canonical moment matrix CM and use the trace of its ...
Anomalies of the magnitude of the bias of the maximum likelihood estimator of the regression slope
(Athens Institute for Education and Research, 2015)
The slope of the best-fit line y h x x 0 1 ( ) from minimizing a function of the squared vertical and horizontal errors is the root of a polynomial of degree four which has exactly two real roots, one positive and ...
An investigation of the performance of five different estimators in the measurement error regression model
(Athens Institute for Education and Research, 2015)
In a comprehensive paper by Riggs et al.(1978) the authors analyse the performances of numerous estimators for the regression slope in the measurement error model with positive measurement error variances >0 0 for X and ...
