lgarchObjective and lgarchRecursion1 are auxiliary functions called by lgarch
. The functions are not intended for the average user.
1 2 | lgarchObjective(pars, aux)
lgarchRecursion1(pars, aux)
|
pars |
numeric vector with the parameters of the ARMA representation |
aux |
auxiliary list |
To understand the structure and content of pars and aux, see the source code of the lgarch
function
lgarchObjective returns the value of the objective function (either the log-likelihood or the residual sum of squares) used in estimating the ARMA representation. lgarchRecursion1 returns the residuals of the ARMA representation associated with the ARMA parameters pars
