ecmSymFit {apt}

Fitting symmetric Error Correction Model

Description

Estimate a symmetric error correction model (ECM) for two time series.

Usage

ecmSymFit(y, x, lag = 1)

Arguments

y

dependent or left-side variable for the long-run regression.

x

independent or right-side variable for the long-run regression.

lag

number of lags for variables on the right side.

Details

The package apt focuses on price transmission between two series. This function estimates a standard error correction model for two time series. While it can be extended for more than two series, it is beyond the objective of the package now.

Value

Return a list object of class "ecm" and "ecmSymFit" with the following components:

y

dependend variable

x

independent variable

lag

number of lags

data

all the data combined for the ECM

IndVar

data frame of the right-hand variables used in the ECM

name.x

name of the independent variable

name.y

name of the dependent variable

ecm.y

ECM regression for the dependent variable

ecm.x

ECM regression for the independent variable
