Description: 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.
