We present an exact test for whether two random variables that have known bounds on their support are negatively correlated. The alternative hypothesis is that they are not negatively correlated. No assumptions are made on the underlying distributions. We show by example that the Spearman rank correlation test as the competing exact test of correlation in nonparametric settings rests on an addi...

The generalized density is a product of a density function and a weight function. For example, the average local brightness of an astronomical image is the probability of finding a galaxy times the mean brightness of the galaxy. We propose a method for studying the geometric structure of generalized densities. In particular, we show how to find the modes and ridges of a generalized density func...

Several political and economic factors are involved in choosing exchange rate policy in Organization of Islamic Cooperation (OIC) countries. In the present study, these factors  have been investigated with an emphasis on OCA and political economic factors during 1990 -2014. The result shows that OCA and political economic factors as well as tradable sector are influential on exchange rate poli...

The aim of this study is to examine the nonlinear effects of fiscal and monetary policies on inflation during 1990:3 to 2013:1 based on threshold model. First lag of the liquidity growth is recognized as threshold variable with threshold value estimated at 6.37 percent. In low liquidity growth, the results indicate that inflation expectations and the lagged liquidity growth are the most importa...

The paper reviews some axioms of additivity concerning ranking methods used for generalized tournaments with possible missing values and multiple comparisons. It is shown that one of the most natural properties, called consistency, has strong links to independence of irrelevant comparisons, an axiom judged unfavourable when players have different opponents. Therefore some directions of weakenin...

tourism industry has been the fastest and the most income-generating industry in the first decade of the third millennium. it has been for many countries including some of oic member countries a source of foreign exchange and contributed into their development. in this paper, we try to test empirically whether tourism expansion has had any significant effect on economic growth of oic member cou...

â â â  â â â â â â â â â â â  financial sector is one of the most influential sectors in economic activities. empirical and theoretical studies conducted in recent years have also confirmed the significant role of financial institutions in economic growth. additionally, trade and financial liberalization policies have been particular concerned with strategic policies in developed and developing...

excessive alveolar bone resorption is commonly found when teeth are extracted. this is a problem in anterior part of mouth because it will result in an unaesthetic pontic on a narrow hollowed out alveolar ridge. yet, another problem is gingival recession and root exposure in adjacent teeth which represent a therapeutic problem to the clinician. use of acellular dermal matrix graft is an appropr...

This paper considers optimization of the ridge parameters in generalized ridge regression (GRR) by minimizing a model selection criterion. GRR has a major advantage over ridge regression (RR) in that a solution to the minimization problem for one model selection criterion, i.e., Mallows’ Cp criterion, can be obtained explicitly with GRR, but such a solution for any model selection criteria, e.g...

An average inter-ridge distance (AID) computation method is proposed, and the average inter-ridge distance is used to classify fingerprint images. This method is experimentally proved to be able to speed up retrieving a fingerprint from the template database that is organized according to the inter -ridge distance. Inter-ridge distance-based classification method has the property of being able ...
