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...

In statistics, the Pearson correlation coefficient rx,y determines the degree of linear correlation between two variables and it is known that −1 ≤ rx,y ≤ 1. In the theory of networks, a curious expression proposed in [PRL 89 208701 (2002)] for degree-degree correlation coefficient rji,ki , i ∈ [1,M ] has been in use. We realize that the suggested form is the conventional Pearson’s coefficient ...

The purpose of this study was to determine if a pharmacology medical history assignment would enable dental students to demonstrate improved knowledge and understanding of pharmacology by researching the drugs their patients were taking and recording pharmacological information in their patients' health records. The study followed a pretest-posttest design and evaluated students' knowledge of t...

Methods Sixty-one asymptomatic children (31 girls, 30 boys) aged 7-9 years (mean 7.9 ±0.8) were assessed once by one observer for the sagittal curvatures of the trunk: thoracic kyphosis (TK), lumbar lordosis (LL) and sacral slope (SS) first with digital photography and with Rippstein plurimeter. Statistical analysis was performed using paired Student t-test, Wilcoxon matched-pairs and Pearson c...

This paper introduces a causation coefficient which is defined in terms of probabilistic causal models. This coefficient is suggested as the natural causal analogue of the Pearson correlation coefficient and permits comparing causation and correlation to each other in a simple, yet rigorous manner. Together, these coefficients provide a natural way to classify the possible correlation/causation...

In this paper we present a method of abrupt cut detection with a novel logic of frames’ comparison. Actual frame is compared with its motion estimated prediction instead of comparison with successive frame. Four different similarity metrics were employed to estimate the resemblance of compared frames. Obtained results were evaluated by standard used measures of test accuracy and compared with e...

background and objectives: life satisfaction is one of the most important indicators for evaluation of mental health status in general population including university students. in this field, the appropriate tool is necessary. so, this study was carried out in order to assess the reliability and validity of the swls in the students of kashan nursing & midwifery faculty (knmf), kashan, iran, in ...
