The following regularity conditions are made. (A.1) X has full rank p and η ∈ Ω where Ω is an open subset of R p+q+1 that contains η 0. (A.2) Γ γ is twice differentiable with respect to γ with continuous second-order derivatives and is positive definite.

We investigated the relationships between leaders' and their followers' psychological capital and organizational identification in a Chinese community. Participants included 423 followers on 34 work teams, each with its respective team leader. Hierarchical linear models (HLM) were used in the analyses to delineate the relationships among participants' demographic background (gender, age, marita...

The general setting of regression analysis is to identify a relationship between a response variable Y and one or several explanatory variables X by using a learning sample. In a prediction framework, the main assumption for predicting Y on a new sample of X observations is that the regression model Y = f(X) + ǫ is still valid. Unfortunately, this assumption is not always true in practice and t...

A family of linear models for learning in two-choice situations is considered. These models have in common the assumption that nonreward has no effect on response probability. The function r(p) that relates asymptotic probability of one of the responses to its initial probability is studied intensively. It is shown to be closely related to the total number x(p) of response alternations. The asy...

The predictive validity of personality for important life outcomes is well established, but conventional longitudinal analyses cannot rule out the possibility that unmeasured third-variable confounds fully account for the observed relationships. Longitudinal hierarchical linear models (HLM) with time-varying covariates allow each subject to serve as his or her own control, thus eliminating betw...

The h-deformed quantum plane is a counterpart of the q-deformed one in the set of quantum planes which are covariant under those quantum deformations of GL(2) which admit a central determinant. We have investigated the noncommutative geometry of the h-deformed quantum plane. There is a 2-parameter family of torsion-free linear connections, a 1-parameter sub-family of which are compatible with a...
