Create a Gram matrix with squared Euclidean distances between observations in the input matrix X and the input matrix Y

Create a Gram matrix with squared Euclidean distances between observations in the input matrix X and the input matrix Y

Arguments

X

A numeric input matrix

Y

A numeric input matrix with the same variables as X

intercept

Logical indicating whether an intercept should be added to the estimation procedure. In this case, the first column is an all-zero column (which will be transformed into an all-ones column in the kernel).
