[PDF File] Canonical Correlation - CMU School of Computer Science
http://5y1.org/file/20128/canonical-correlation-cmu-school-of-computer-science.pdf
Canonical correlation analysis (CCA) is a way of measuring the linear relationship between two multidimensional variables. It finds two bases, one for each variable, that are optimal with respect to correlations and, at the same time, it finds the corresponding correlations. In other words, it finds the two bases in which the correlation matrix …

http://5y1.org/file/20128/lecture-16-correlation-and-regression-duke-university.pdf
Correlation describes the strength of the linear association between two variables. It takes values between -1 (perfect negative) and +1 (perfect positive). A value of 0 indicates no linear association. We use to indicate the population correlation coe to indicate the sample correlation coe cient. cient, and R or r.

Distance correlation: Distance correlation measures both linear and non-linear associ-ation between two random variables or random vectors. This is in contrast to Pearson’s correlation, which can only detect linear association between two random variables.
[PDF File] Microsoft Word - Simple Linear Correlation (revised).docx
http://5y1.org/file/20128/microsoft-word-simple-linear-correlation-revised-docx.pdf
Simple linear correlation is a measure of the degree to which two variables vary together, or a measure of the intensity of the association between two variables. Correlation often is abused. You need to show that one variable actually is affecting another variable. The parameter being measure is (rho) and is estimated by the statistic r, the ...
[PDF File] ppcor: Partial and Semi-Partial (Part) Correlation
http://5y1.org/file/20128/ppcor-partial-and-semi-partial-part-correlation.pdf
Partial correlation is the correlation of two variables while controlling for a third variable. When the determinant of variance-covariance matrix is numerically zero, Moore-Penrose generalized matrix inverse is used. In this case, no p-value and statistic will be provided if the number of variables are greater than or equal to the sample size.
[PDF File] Multiset Canonical Correlation Analysis simply explained
http://5y1.org/file/20128/multiset-canonical-correlation-analysis-simply-explained.pdf
Canonical correlation analysis (CCA) was first introduced by Hotelling (1936) with the goal of identifying projections of two datasets that are maximally correlated. Hotteling’s approach was to maximize Pearson’s correlation coefficient and to require that multiple projections be uncorrelated from one another. This formulation results in a closed-form solution …

Correlation coefficients (denoted r) are statistics that quantify the relation between X and Y in unit-free terms. When all points of a scatter plot fall directly on a line with an upward incline, r = +1; When all points fall directly on a downward incline, r = !1. Such perfect correlation is seldom encountered.

[PDF File] Canonical Correlation Analysis when the Data are Curves
http://5y1.org/file/20128/canonical-correlation-analysis-when-the-data-are-curves.pdf
It is not immediately straightforward to extend canonical correlation analysis to the context of functional data analysis, where the data are themselves curves or functions. The obvious approach breaks down, and it is necessary to use a method involving smoothing in some way. Such a method is introduced and discussed with reference to a data set on human …
