For time series comparisons, it has often been observed that z-score normalized Euclidean distances far outperform the unnormalized variant. In this paper we show that a z-score normalized, squared Euclidean Distance is, in fact, equal to a distance based on Pearson Correlation. This has profound impact on many distance-based classification or clustering methods. In addition to this theoretical...

introduction: child mortality indices are key element that reflects health status of societies and inform policy makers to take suitable policies to reduce them. this study was performed to examine the main determinants of under-5 mortality rate (u5mr) in oecd countries in two cross-sections, 2010 and 2013, and the results of them was compared. material and methods: this was a cross- sectional ...

 The study had the objective of analyzing psychometric properties Brief Academic Procrastination Scale (EBPA-16). The sample was non-probabilistic and intentional, represented by 478 university students (59.8% women 40.2% men) from Lima Sur, aged between 18 33 years. instrumental type, where EBPA-16 constructed applied, made up 16 items distributed in two dimensions, with a Lickert-type re...

We construct a Pearson correlation-based network and a partial correlationbased network, i.e., two minimum spanning trees (MST-Pearson and MST-Partial), to analyze the correlation structure and evolution of world stock markets. We propose a new method for constructing the MST-Partial. We use daily price indices of 57 stock markets from 2005 to 2014 and find (i) that the distributions of the Pea...

The Pearson correlation coefficient based on the customer relationship clearly illustrate to the product development process. It developed in an association from the customer relationship management process. The CRM should be implemented to the Pearson correlation algorithm. In an existing system is used to implement for a customer association management in an organization process implement for...

irrigation management transfer (imt) is under implementation within 63 countries over the world. the results and constraints of this event have been different in mentioned countries. this research objected to survey of imt constraints and identifies its key indicators in ghazvin and moghan pilots with different characteristics in type of irrigation and their imt process. the research method is ...
