Background of canonical correlation analysis Canonical correlation analysis may be used to investigate a number of questions including the extent to which one set of two or more variables can be predicted or explained by another set of two or more variables (Thompson 1984). Tatsouka (1973) ...

for the other canonical variate. Wilks's lambda is commonly used to test the significance of canonical correlation. Analogous with ordinary correlation, canonical correlation squared is the percent of variance in the dependent set explained by the independent set of variables along a given dimension ...

Cumulative Percent Explained This column indicates the cumulative percentage of the variation in the designated set of variables that is explained by this canonical variate and those listed above it. Canonical Correlation Squared The square of the canonical correlation coefficient. This is repeated from ...
7.2.1.7.2Redundancy analysis (RDA) RDA was also named asprincipal component analysiswithinstrumental variables.534As a constrained ordination, RDA was developed to assess how much of the variation in one set of variables can be explained by the variation in another set of variables. However,...
explained changes in cerebral total haemoglobin (HbT) measured by NIRS. Ejike et al. [3] reported that the regional cerebral oxygenation presented a negative correlation with arterial partial pressure of CO2(pCO2) and no significant correlation with changes in ECMO flow. Papademetriou et al. [4]...
correlation framework without more prior knowledge of which type of omic data is explained or regressed by the another one (e.g.,with transcripts and metabolites). It is more applicable for exploring the correlated information from the paired omic data sets by CCA method. However, the ...
Thirteen percent of birth size variability was explained by the composite score of the maternal factors (Redundancy, RY/X = 0.131). Given an ability to accommodate numerous relationships and reduce complexities of multiple comparisons, CCA identified the 5 maternal variables able to predict birth...
