NHMSAR (version 1.4)

Estep.MSAR.VM:

Description

Forward-backward algorithm called in fit.MSAR.

Usage

Estep.MSAR.VM(data, theta, smth = FALSE, verbose = FALSE, 
   covar.emis = NULL, covar.trans = NULL)

Arguments

data

array of univariate or multivariate series with dimension T*N.samples*d. T: number of time steps of each sample, N.samples: number of realisations of the same stationary process, d: dimension.

theta

model's parameter; object of class MSAR. See also init.theta.MSAR.

smth

If smth=FALSE, only the forward step is computed for forecasting probabilities. If smth=TRUE, the smoothing probabilities are computed too.

verbose

covar.emis

covariables for emission probabilities.

covar.trans

covariables for transition probabilities

Value

list including

loglik

log likelihood

probS

smoothing probabilities: \(P(S_t=s|y_0,\cdots,y_T)\)

probSS

one step smoothing probabilities: \(P(S_t=s,S_{t+1}|y_0,\cdots,y_T)\)
