In onnokleen/mfGARCH: Mixed-Frequency GARCH Models

This function simulates a GARCH-MIDAS model. Innovations can follow a standard normal or student-t distribution.

Description

This function simulates a GARCH-MIDAS model. Innovations can follow a standard normal or student-t distribution.

Usage

simulate_mfgarch(
  n.days,
  mu,
  alpha,
  beta,
  gamma,
  m,
  theta,
  w1 = 1,
  w2,
  K,
  psi,
  sigma.psi,
  low.freq = 1,
  n.intraday = 288,
  student.t = NULL,
  corr = 0
)

Arguments

n.days	number of days
mu	mu
alpha	alpha
beta	beta
gamma	gamma
m	m
theta	theta
w1	w1
w2	w2
K	K
psi	psi
sigma.psi	sigma.psi
low.freq	number of days per low-frequency period
n.intraday	number of maximum intraday returns
student.t	either NULL or degrees of freedom
corr	correlation between innovations (should only be used for daily tau)

Examples

simulate_mfgarch(n.days = 200, mu = 0, alpha = 0.06, beta = 0.92, gamma = 0, m = 0,
theta = 0.1, w1 = 1, w2 = 3, K = 12, psi = 0.98, sigma.psi = 0.1, low.freq = 10)
