First canonical correlation
WebThe first column of U and V contains the first canonical variables. The key properties of U and V is that the correlation between the first canonical variables is the highest correlation you can achieve with this dataset when characterizing linear relationships. WebFirst, we instantiate CCA object and use fit () and transform () functions with the two standardized matrices to perform CCA. 1 2 3 ca = CCA () ca.fit (X_mc, Y_mc) X_c, Y_c = ca.transform (X_mc, Y_mc) And our result is …

WebCanonical correlations are generalizations of simple correlations between individual variables to correlations between groups. In this case, canonical correlations are found between blood test results as a group and MRI/LP results as a group for each form of meningitis and may then be compared with one another.
