Hartlap correction
WebThis however raises the task of finding an equivalent to the Kaufman-Hartlap correction for such a mixture of estimated and analytic matrices. More recently, Joachimi (2024) describes a non-linear extension of that estimator which combines covariance estimates from two sets of independent data vector realizations and hence does not require a ...
