A new method to evaluate the similarity of chromatographic fingerprints: weighted pearson product-moment correlation coefficient.
The Pearson product-moment correlation coefficient is being used to evaluate the similarity of the high-performance liquid chromatographic fingerprints of traditional Chinese medicine (TCM) in China. It is confirmed that a large range of peak areas produced the wrong results. A new algorithm concerning weighted Pearson product-moment correlation coefficient is proposed in this article. The resu...
متن کاملUsing Transitivity to Increase the Accuracy of Sample-Based Pearson Correlation Coefficients
Pearson product-moment correlation coefficients are a wellpracticed quantification of linear dependence seen across many fields. When calculating a sample-based correlation coefficient, the accuracy of the estimation is dependent on the quality and quantity of the sample. Like all statistical models, these correlation coefficients can suffer from overfitting, which results in the representation...
متن کاملBrownian distance covariance
Distance correlation is a new class of multivariate dependence coefficients applicable to random vectors of arbitrary and not necessarily equal dimension. Distance covariance and distance correlation are analogous to product-moment covariance and correlation, but generalize and extend these classical bivariate measures of dependence. Distance correlation characterizes independence: it is zero i...
متن کاملA New Robust Blind Watermarking Scheme Based on Steerable pyramid and DCT using Pearson product moment correlation
In this paper, we present a new, robust digitalwatermarking scheme for ownership protection. Thescheme is based on Steerable Pyramid (SP) and discretecosine transform (DCT) using Pearson product momentcorrelation. During the process of watermark embedding,SP is performed on original host image, and correspondingoriented sub-band is selected to carry the watermark. DCT<lb...
متن کاملSeeing the Fisher Z - Transformation
Since 1915, statisticians have been applying Fisher’s Z-transformation to Pearson product-moment correlation coefficients. We offer new geometric interpretations of this transformation.
