SVM: Constructor of an Stochastic volatility model object

Description

Constructor of the Stochastic Volatility model (SVM) for Bayesian estimation in Stan.

Usage

SVM(ts,arma = c(0,0),xreg = NULL,series.name = NULL)

Arguments

ts

a numeric or ts object with the univariate time series.

arma

Optionally, a specification of the ARMA model,same as order parameter: the two components (p, q) are the AR order,and the MA order.

xreg

Optionally, a numerical matrix of external regressors, which must have the same number of rows as ts. It should not be a data frame.

series.name

an optional string vector with the time series names.

Value

The function returns a list with the data for running stan() function of rstan package.

Details

The function returns a list with the data for running stan() function of rstan package.
