Description

This function computes the probability forecasted density function of a univariate HMM for multiple horizons, given observations up to time n

Usage

1
ForecastHMMPdf(y, family, theta, Q, eta, k = 1, graph = 0)

Arguments

y

points at which the pdf function is computed

family

distribution name; run the function distributions() for help

theta

parameters; (r x p)

Q

probability transition matrix; (r x r)

eta

vector of the estimated probability of each regime at time n; (1 x r)

k

prediction times (may be a vector of integers).

graph

(0 or else) produce plots

Value

pdf

values of the pdf function

family = "gaussian"

lb = -6
ub = 6

theta = matrix(c(-1.5, 1.7, 1, 1),2,2)
Q = matrix(c(0.8, 0.3, 0.2, 0.7), 2, 2)
eta = c(0.96091218, 0.03908782)


forecastedhmmpdf = ForecastHMMPdf(y=seq(from=lb, to=ub, by=0.1), family=family,
theta=theta, Q=Q, eta=eta, k=c(1,5,10,20), graph=1)
