coef.qgarch

Extract coefficients from a qgarch model

Fits quadratic generalized autoregressive conditional
heteroskedasticity-in-mean (QGARCH-M) models motivated by Campbell and
Hentschel (1992). The package supports models with lambda fixed at zero,
lambda restricted to a function of the remaining parameters, lambda
estimated freely, and a threshold extension with state-dependent lambda.
It also provides tools for starting values, estimation, forecasting,
likelihood-ratio testing, moment diagnostics, and replication with the
included monthly U.S. stock market dataset.
