ESTIMATION OF THE KULLBACK-LEIBLER DIVERGENCE

open access: yes, 2003
The Kullback-Leibler (KL) divergence K(fl, P) between a set O of probability measures (PMs) on ]R d and some PM P cannot be estimated by K(O, Pn) when O contains PM whose support is not included in the support of the empirical measure Pn. We propose an estimation procedure which avoids any smoothing of Pn.

On the Kullback-Leibler information divergence of locally stationary processes

open access: yes
A class of processes with a time varying spectral representation is established. As an example we study time varying autoregressions. Several results on the asymptotic norm behaviour and trace behaviour of covariance matrices of such processes are ...
