MEM-MIDAS-X one-step-ahead predictions (with skewness parameter)

Description

Predicts the dependent variable, usually the realized volatility, for the MEM-MIDAS-X, with an asymmetric term linked to past negative returns and an additional X part (for instance, the VIX).

Usage

MEM_MIDAS_X_pred(param, x, daily_ret, mv_m, K, z)

Arguments

param	Vector of starting values
x	Dependent variable, usually the realized volatility. It must be positive and "xts" object
daily_ret	Daily returns, which must be an "xts" object, and with the same length of x
mv_m	MIDAS variable already transformed into a matrix, through mv_into_mat function
K	Number of (lagged) realizations of the MIDAS variable to consider
z	Additional daily variable which must be an "xts" object, and with the same length of x

Value

The resulting vector is the log-likelihood value for each i,t
