Under the conditions of OLS use in order to perform multiple linear regressions, both the estimated parameters values and also computed values of some statistical tests such as coefficient of determination, Fisher test or Student test are influenced by collinearity1. The respective influence is...

In this paper, we propose a new model with random variance components for estimating small area characteristics. Under the proposed model, we derive the empirical best linear unbiased estimator, an approximation to terms of order and an estimator whose bias is of order for its mean squared...

The growth rate of different economies in Europe depends strongly on the production and, especially, on the consumption of energy resources. As an empirical rule, the development of such economies is closely interrelated with a consistent CO2 emission into atmosphere. However, this aspect has a...
