sim.unrestricted: Simulate data from an unrestricted factor model

In fnets: Factor-Adjusted Network Estimation and Forecasting for High-Dimensional Time Series

Simulate data from an unrestricted factor model

Description

Simulate the common component following an unrestricted factor model that does not admit a restricted representation; see the model (C1) in Barigozzi, Cho and Owens (2024+)

Usage

sim.unrestricted(n, p, q = 2, heavy = FALSE)

Arguments

n	sample size
p	dimension
q	number of unrestricted factors
heavy	if heavy = FALSE, common shocks are generated from rnorm whereas if heavy = TRUE, from rt with df = 5 and then scaled by sqrt(3 / 5)

Value

a list containing

data	ts object with n rows and p columns
q	number of factors
