In statistics, canonical-correlation analysis (CCA), also called canonical variates analysis, is a way of inferring information from cross-covariance matrices.If we have two vectors X = (X 1, ..., X n) and Y = (Y 1, ..., Y m) of random variables, and there are correlations among the variables, then canonical-correlation analysis will find linear combinations of X and Y that have a maximum ...
In multivariate analysis, canonical correspondence analysis (CCA) is an ordination technique that determines axes from the response data as a unimodal combination of measured predictors. CCA is commonly used in ecology in order to extract gradients that drive the composition of ecological communities.
In statistics, the generalized canonical correlation analysis (gCCA), is a way of making sense of cross-correlation matrices between the sets of random variables when there are more than two sets. While a conventional CCA generalizes principal component analysis (PCA) to two sets of random variables, a gCCA generalizes PCA to more than two sets ...

Canonical correlation analysis (CCA), non-negative matrix factorization (NMF) and manifold alignment are popular approaches for joint dimensionality reduction. Tools that use CCA or its derivative sparse CCA, such as Seurat3 [ 25 ] and bindSC [ 26 ] identify linear relationships between datasets by identifying linear combinations of variables ...

An analysis of clinical trials found that people who took at least a gram a day of vitamin C when they had a cold reduced the severity of their cold by 15% and had symptoms for slightly less time ...
The idea probably dates back to Hrishikesh D. Vinod's publication in 1976 where he called it "Canonical ridge". [1] [2] It has been suggested for use in the analysis of functional neuroimaging data as such data are often singular. [3] It is possible to compute the regularized canonical vectors in the lower-dimensional space. [4]
