I. Fazekas et F. Liese, SOME PROPERTIES OF THE HELLINGER TRANSFORM AND ITS APPLICATION IN CLASSIFICATION PROBLEMS, Computers & mathematics with applications, 31(8), 1996, pp. 107-116
The Hellinger transform for stochastic processes is studied. The Helli
nger transform is calculated for multidimensional Gaussian autoregress
ive processes and for Ornstein-Uhlenbeck processes.
