Computes standardized scores from an SVD result performed by svd_wrapper.
These scores are scaled to have approximately unit variance, assuming the original
data used for SVD was centered. They differ from the s component of the
svd object, which contains scores scaled by singular values.
# S3 method for svd
std_scores(x, ...)A matrix of standardized scores (N x k) with columns having variance close to 1.
An object of class svd, typically from svd_wrapper.
