The Stuttering Generalized Waring Distribution arises in connection with sampling from an urn that contains balls of two colours (black and white) ant it can be thought of as an intermingling of generalized Waring streams (Panaretos and Xekalaki [4]). Because of its application potential a study...

Compound Poisson distributions (CPD's) are frequently used as alternatives in studying situations where a simple Poisson model is found inadequate to describe. In this paper an attempt is made to identify compound Poisson distributions when it is known that the conditional distribution of two...

Nonparametric methods have been very popular in the last couple of decades in time series and regression, but no such development has taken place for spatial models. A rather obvious reason for this is the curse of dimensionality. For spatial data on a grid evaluating the conditional mean given...

The paper discusses extensions of the well-known hypergeometric and negative hypergeometric distributions for describing data with multiple counts. The derivation of these extensions is based on certain urn schemes that allow for sampling clusters of items rather than individual items. The...

Tests results for causality between energy consumption and economic growth do not have a consensus in the financial economics literature. Empirical evidence varies on the economies examined and methodology employed. This paper proposes a wavelet analysis as a semi- parametric model for detecting...

The EWMA control chart is used to detect small shifts in a process. It has been shown that, for certain values of the smoothing parameter, the EWMA chart for the mean is robust to non normality. In this article, we examine the case of non normality in the EWMA charts for the dispersion. It is...

Autoregressive Conditional Heteroskedasticity (ARCH) models have been applied in modeling the relation between conditional variance and asset risk premium. The most important theoretical regularities that govern the dynamic structure of financial time series are presented. A model named...

The Republic of Mozambique is experiencing a significant social and economic change and needs an updated informative base to allow policy-makers to found their decision on reliable and comparable data. The fast development of the Non Observed Economy (NOE) was one of the most important...

The study examines the effect of income and education of the household on its health expenditure, based on primary data collected from Jajpur district of Orissa. Multi-stage random sampling method is adopted to select households (HHs), i.e., sampling unit. The descriptive statistics shows that...

Hayek´s methodological outlook at the time he engaged in business cycle research was actually closer to praxeological apriorism than to Popperian falsificationism. A consideration of the Duhem thesis highlights the fact that even from a mainstream methodological perspective falsificationism is...
