rowCorr

rowCorr(X, Y)

Please see rowFunctions for the parameters and calculation rules.

Calculate the correlation between X and Y by row and return a vector with the same number of rows of X. NULL values are ignored in calculation.

m1=matrix(2 -1 4, 8 3 2, 9 0 1)
m2=matrix(8 11 10, 8 17 4, 14 6 4)
rowCorr(m1, m2)
// output
[0.61, 0.7559, 0.9449]

m3=matrix(8 NULL 10, 8 NULL 4, 14 NULL NULL)
rowCorr(m1, m3)
// output
[0.61, , 1]

a=array(DOUBLE[], 0, 10).append!([1 2 3, 4 NULL 5, 6 7 8, NULL 3 10]);
b=array(DOUBLE[], 0, 10).append!([[1.3,1.2, 4], [1.0,1.4, 2], [1.1, 1.4, 3],[1, 4, 7]]);

rowBeta(a, b)
// output
[0.535, 1 , 0.9105, 2.3333]
