Object of class |
This function evaluates the the matrix \hat{A}
of the smoothed log-concave maximum
likelihood estimator, which is positive definite, and equals the difference between the
sample covariance matrix and the covariance matrix of the fitted log-concave maximum
likelihood density estimator.
