Hypothesis testing in a generic nesting framework for general distributions

Martín, N.; Balakrishnan, N. - In: Journal of Multivariate Analysis 118 (2013) C, pp. 1-23

Nested parameter spaces, either in the null or alternative hypothesis, often enable an improvement in the performance of the tests. In this context, order restricted inference has not been studied in detail. Divergence based measures provide a flexible tool for proposing some useful test...

Handling equality constraints in evolutionary optimization

Barkat Ullah, Abu S.S.M.; Sarker, Ruhul; Lokan, Chris - In: European Journal of Operational Research 221 (2012) 3, pp. 480-490

optimization problems using evolutionary algorithms (EAs). However, the presence of equality constraints makes the feasible space … very small compared to the entire search space. As a consequence, the handling of equality constraints has long been a … emphasis on equality constraints. The basic concept of the new technique is to reach a point on the equality constraint from …

More on partitioned possibly restricted linear regression

Werner, Hans Joachim; Yapar, Cemil - University of Bonn, Germany - 1994

This paper deals with the general partitioned linear regression model where the regressor matrix $X=\pmatrix{X_1 & X_2\cr}$ may be deficient in column rank, the dispersion matrix $V$ is possibly singular, $\beta^t=\pmatrix{\beta_1^t & \beta_2^t\cr}$ - being partitioned according to $X$ - is the...
