The time-varying parameter model
2022This chapter introduces a general form of the time-varying parameter (TVP) model. Unlike most traditional econometric models, which are based on fixed-parameter estimation, the TVP model can capture the dynamics of parameters over the sample period based on the recursive Kalman filter (KF) algorithm. When applied to tourism demand analysis, this unique

ON THE STABILITY OF SYSTEMS WITH MIXED TIME-VARYING PARAMETERS
International Journal of Robust and Nonlinear Control, 1997Summary: The well-known scaled small gain condition guarantees stability for a linear time invariant system subject to bounded complex nonlinear and/or time-varying perturbations. A polynomial time computable condition is derived that can be substantially less conservative for gain scheduled and other multivariable systems with repeated real time ...

Stability of Circuits With Randomly Time-Varying Parameters
IRE Transactions on Circuit Theory, 1959This paper is concerned with the stability, in a stochastic sense, of circuits or systems described by ordinary differential equations with randomly time varying parameters. Sufficient conditions for stability in the mean square are obtained by an extension of "Lyapunov's Second Method" to stochastic problems.

Time-varying parameters: a critical introduction
Structural Change and Economic Dynamics, 1995Abstract One of the assumptions behind standard econometric techniques is that coefficients are fixed throughout the whole sample period or over all the cross-sectional units. This implies that the economic structure generating the data does not change, but the parameters characterizing the micro-units, along with their aggregate counterparts, do ...

STATISTICAL LEARNING WITH TIME-VARYING PARAMETERS
Macroeconomic Dynamics, 2003In their landmark paper, Bray and Savin note that the constant-parameters model used by their agents to form expectations is misspecified and that, using standard econometric techniques, agents may be able to determine the time-varying nature of the model's parameters.

Adaptive identification algorithms for time-varying parameters
Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002Adaptive identification of rapidly changing parameters is essentially needed in adaptive signal processing and adaptive control. New accelerated LMS and RLS type of adaptive algorithms are given from a standpoint that any parameter changes can be approximately expressed by a finite degree of polynomial function of time.

Selected Structures of Filters With Time-Varying Parameters
IEEE Transactions on Instrumentation and Measurement, 2007One important problem of signal processing in measurement systems is designing a filter that possesses a linear-phase response and, at the same time, has a short transient state. This paper presents the methodology of varying, in the time parameters, a low-pass Bessel filter and a filter of a constant component.
