simulate_observations: Simulate state-dependent observations

In fHMM: Fitting Hidden Markov Models to Financial Data

Simulate state-dependent observations

Description

This function simulates state-dependent observations.

Usage

simulate_observations(
  markov_chain,
  sdd,
  mus,
  sigmas,
  dfs = NULL,
  seed = NULL,
  total_length = length(markov_chain)
)

Arguments

markov_chain	A numeric vector of states of a Markov chain.
sdd	A character, the name of the state-dependent distribution, one of "t", "gamma", and "lnorm".
mus	A numeric vector of expected values.
sigmas	A numeric vector of standard deviations.
dfs	A numeric vector of degrees of freedom. Only relevant if sdd = "t".
seed	Set a seed.
total_length	An integer, the total length of the output vector. Must be greater or equal than length(markov_chain).

Value

A numeric vector of length total_length, where the first length(markov_chain) elements are numeric values and the last total_length - length(markov_chain) elements are NA_real_.
