Online System Identification Method Using Modified Regularized Exponential Forgetting [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 The paper deals with the use of regularized exponential forgetting (REF) in the process of online system identification. The deployment of this type of forgetting strategy is advantageous for very long runs with small changes in the identified input ...

Generic Advertising Wearout: The Case of the New York City Fluid Milk Campaign
Journal of Agricultural and Resource Economics, 1996 This article examines two major generic fluid milk advertising campaigns in New York City during the 1986-92 period. Estimates from a time-varying parameter model show that the evolution of the impact of generic advertising on fluid milk sales over each ...
