sim.restricted {fnets}

Simulate data from a restricted factor model

Description

Simulate the common component following an unrestricted factor model that admits a restricted representation; see the model (C2) in the reference.

Usage

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

Arguments

n

sample size

p

dimension

q

number of unrestricted factors; number of restricted factors is given by 2 * q

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

r

number of restricted factors
