VC - A method for estimating time-varying coefficients in linear models

Abstract

This paper describes a moments estimator for a standard state-space model with coefficients generated by a random walk. This estimator does not require that disturbances are normally distributed, but if they are, the proposed estimator is asymptotically equivalent to the maximum likelihood estimator.

In the meanwhile I became aware of some errata. I attach the file with the errata marked and hyperlinked with apologies especially to the referees.


Anonymous - Another erratum

I found another mistake: I gave again wrong dimensions for the vectors v and v_i. I attach a corrected version with my apologies.
If a reader or a referee finds some problems like that, you may ask in an anonymous comment and I will quickly respond (and correct, if necessary).
