Generalized autoregressive method of moments
Creal, Drew; Koopman, Siem Jan; Lucas, André; … - 2015
We introduce a new estimation framework which extends the Generalized Method of Moments (GMM) to settings where a subset of the parameters vary over time with unknown dynamics. To filter out the dynamic path of the time-varying parameter, we approximate the dynamics by an autoregressive process...
