Interpretation of correlation coefficients.

چکیده
A recently published article by Ko et al1 illustrates a commonly encountered problem with the interpretation of correlation coefficients in medical research. The authors stated the correlation coefficient ranged from -0.002 to 0.15. If the P value was greater than 0.05, they interpreted the findings as indicating no correlation. Otherwise, there was weak correlation. The t value of the correlation coefficient was given by:

متن کاملEstimation of Hydrodynamic Coefficients of Zouzan Plain Aquifer Using of Electrical Sounding Data
Knowledge of hydrodynamic coefficients is necessary for the determination of natural water flow through an aquifer and management of ground water resource. In this study, in order to determination of hydrodynamic coefficients of Zouzan aquifer results of 112 electrical sounding have been used. Quantitative interpretation was done by using IPI2WIN. Values of formation factor and porosity were de...
متن کاملCloseness to Identity: A Conceptual Framework for the Definition and Interpretation of Correlations
This paper introduces a way of understanding correlation coefficients based on the notion of scaled-score similarity (i.e., closeness to identity). It is suggested that the proposed framework has intuitive al)peal. It points to the equivalence among various correlation coefficients by showing that correlation problems involve the notion of agreement between interval or ordinal measures expresse...

متن کاملSurvey on Wavelet Statistics
• Why the wavelet coefficients were assumed independent and non-Gaussian [1, 2, 3, 4, 5]? Because of the WT primary properties: (locality, multiresolution and compression) and interpretation of the WT as a whitening process which attempts to make the coefficients statistically independent. • Why the coefficients are assumed jointly Gaussian [6, 7, 8]? Because it helps to captures the linear cor...
