In this study we examine in covariance stationary time series the consequences of constructing confidence intervals for the population mean using the classical methodology based on the hypothesis of independence. As criteria we use the actual probability the confidence interval of the classical...

In simple random sampling, the basic assumption at the stage of estimating the standard error of the sample mean and constructing the corresponding confidence interval for the population mean is that the observations in the sample must be independent. In a number of cases, however, the validity...

This study is focused on the construction of long – term scenarios for the transition to renewable energy. Utilizing European and national targets, the key objective of this work is to investigate how these targets are reflected in both economic and environmental terms. The constructed model...

This paper by using the system of LEAP (Long range Energy Alternatives Planning System) constructs four different energy scenarios for the Greek transport, energy and industry sectors. By projecting the renewable energy use for the years 2020 and 2030 and the associated resulting carbon dioxide...

This paper presents the dimensions of the climate change problem and its economic effects as well as the evolution of the international meetings to cope with it. In these lines it discusses the use of Integrated Assessment Models (IAMs), the damage cost estimates and various other issues related...
