In this paper, an evaluation method is suggested for selecting one of two competing models based on certain predictive ability ratings. The main focus is on the case of linear models that are not necessarily nested. In the context of such models, the test procedure is based on a sample statistic...

The paper deals with a distribution that arises as the distribution of a sample statistic used to compare the predictive ability of two competing linear models. It is defined as the distribution of the ratio of two correlated gamma variables and its probabilities are tabulated in order that they...

This chapter is based on qualitative focus group and in-depth interview data collected among rural residents and urban migrants in the five focus countries for this study. The chapter documents the relationship between climate change and internal human mobility as seen by the population, as well...

Climate change is a major source of concern in the Middle East and North Africa (MENA) region, and migration is often understood as one of several strategies used by households to respond to changes in climate and environmental conditions, including extreme weather events. Other coping and...

A large part of this study is based on data collected in 2011 in five focus countries of the MENA region. In addition, other existing data sources were used as well, as documented in the various chapters that follow, but this need not be discussed in this chapter. This chapter documents the...

What are the coping mechanisms and adaptation strategies (apart from migration which is discussed in part III of the study) that households use in order to respond to changes in climate and environmental conditions? Are households forced to sell assets or take other emergency measures in cases...

This study aims to be relevant for the MENA region as a whole, but it focuses on five countries - Algeria, Egypt, Morocco, Syria, and Yemen, and in many (but not all) cases on specific geographic areas within each of the five countries. After a brief introduction, this chapter outlines the...

The paper considers the problem of selecting one of two not necessarily nested competing regression models based on comparative evaluations of their abilities in each of two different issues: The first pertains to viewing the problem as a “best-fitting” model determination problem in the...
