Hi R Users,
following the work of Fleming, Kirby and Ostdiek (2001, you can find the
), I would like to estimate the conditional covariance matrax using an
exponentially weighted methods like:
where e_t is the Kx1 vector of returns at time t and the parameter /alpha
/has to be estimated. The /alpha /can be considered the decay rate the
maximizes the likelihood function:
Is there an R package that can be useful for me??
Thanks in advance for the help!!
