Abstract

We consider the problem of tracking an unstable stochastic process XtX_t by using causal knowledge of another stochastic process YtY_t. We obtain necessary conditions and sufficient conditions for maintaining a finite tracking error. We provide necessary conditions as well as sufficient conditions for the success of this estimation, which is defined as order mm moment trackability. By-products of this study are connections between statistics such as R\'{e}nyi entropy, Gallager's reliability function, and the concept of anytime capacity.
