Implications of Dimensionality on Measurement Reliabilitye aspects within a measurement framework focusing on one hand on the dimensionality of the measurement model and on the other hand on the dimensionality of the measurement scale. Working through theorems and examples we compare two reliability estimators, namely Cronbach‘s alpha and Tarkkonen‘s rho.

More on the F-test under Nonspherical Disturbanceselation, and that the conservative variant is more likely to occur for extreme values of the spatial autocorrelation parameter. In particular, it will wipe out the progressive one as the sample size increases.

Minimum Description Length Model Selection in Gaussian Regression under Data Constraints and a component that may be interpreted as the parametric complexity of the model. The stochastic complexity for the data, relative to a suggested model, serves as a criterion for model selection. The calculation of the stochastic complexity can be considered as an implementation of the minimum des

Self-exciting Extreme Value Models for Stock Market Crashesice in EVT is to compute either unconditional quantiles of the loss distribution or conditional methods linking GARCH models to EVT. Our approach combines self-exciting models for exceedances over a given threshold with a marked dependent process for estimating the tail of loss distributions. The co

Consumption and Income: A Spectral Analysis the data, using a variety of spectral methods that depend on the concepts of Fourier analysis. It is found that fluctuations in the rate of growth of consumption tend to precede similar fluctuations in income, which contradicts a common supposition. The difficulty is emphasised of uncovering from t

Improved Estimation Strategy in Multi-Factor Vasicek Modelon methodology for the drift parameters when homogeneity of several such parameters may hold. However, it is possible that the information regarding the equality of these parameters may not be accurate. In this context, we consider .

Bounds on Expected Coupling Times in a Markov Chainto find explicit expressions for the expected time to coupling in a general Markov chain. In this paper simple upper and lower bounds are given for the expected time to coupling in a discrete time finite Markov chain. Extensions to the bounds under additional restrictive conditions are also given wi
