Econometrics Toolbox

Model and analyze financial and economic systems using statistical methods

Econometrics Toolbox? provides functions for modeling economic data. You can select and calibrate economic models for simulation and forecasting. For time series modeling and analysis, the toolbox includes univariate ARMAX/GARCH composite models with several GARCH variants, multivariate VARMAX models, and

cointegration analysis. It also provides methods for modeling economic systems using state-space models and for estimating using the Kalman filter. You can use a variety of diagnostic functions for model selection, including hypothesis, unit root, and stationarity tests.

Univariate Time-Series Modeling

Time-series modeling capabilities in Econometrics Toolbox are designed to capture characteristics commonly associated with financial and econometric data, including data with fat tails, volatility clustering, and leverage effects.

Supported conditional mean models include:

?Autoregressive moving average (ARMA)

?Autoregressive moving average with exogenous inputs (ARMAX)

?Autoregressive integrated moving average (ARIMA) with exogenous inputs (ARIMAX)

?Regression with ARIMA error terms

Supported conditional variance models include:

?Glosten-Jagannathan-Runkle (GJR)

?Exponential GARCH (EGARCH)

Multiple Time-Series Modeling

Econometrics Toolbox supports multivariate time-series analysis by extending capabilities for univariate models. Supported models include:

?Vector autoregressive (VAR)

?Vector moving average (VMA)

?Vector autoregressive moving average (VARMA)

?Vector autoregressive moving average with exogenous inputs (VARMAX)

Model Identification and Analysis

With Econometrics Toolbox, you can select and test models by specifying a model structure, identifying the model order, estimating parameters, and evaluating residuals. A variety of pre- and post-estimation diagnostics and tests support these analyses, including:

?Likelihood ratio, Wald, and Lagrange multiplier tests for model specification

?Akaike and Bayesian information criteria for model order selection

?Engle’s test for the presence of ARCH/GARCH effects

?Sample autocorrelation, cross-correlation, and partial autocorrelation functions

?Ljung-Box Q (portmanteau) test for autocorrelation

?Dickey-Fuller and Phillips-Perron unit root tests

?KPSS and Leybourne-McCabe stationarity tests

?Engle-Granger and Johansen tests for cointegration

?Variance ratio test for random walks

State-Space Modeling and Parameter Estimation

Econometrics Toolbox includes functions for creating state-space models and tools for estimating parameters based on these and other model types.

State-Space Modeling

Econometrics Toolbox provides functions for modeling time-invariant or time-varying, linear, Gaussian

state-space models. You can create state-space models with known parameter values, perform Monte-Carlo simulations, and generate forecasts from the model. For models with unknown parameter values, you can perform parameter estimation from full data sets or data sets with missing data using the Kalman filter.

Parameter Estimation

With Econometrics Toolbox, you can perform parameter estimation (also known as model calibration) of univariate ARMAX/GARCH composite models, multivariate VAR/VARX models, multivariate VEC models, and

state-space models.

Monte Carlo Simulation

Econometrics Toolbox lets you perform Monte Carlo simulations to generate forecast distributions of both single and multiple time-series models, including univariate ARMAX/GARCH composite models,multivariate VARMAX models, and state-space models.

Forecasting

You can forecast market trends to make budgeting, planning, investing, and policy decisions.Financial Toolbox?provides the foundation for working with financial time-series data; performing regression and parameter estimation with or without missing data; and simulating different scenarios to estimate risk. Econometrics Toolbox extends this foundation with advanced capabilities that account for nonuniform variance across time.

Cointegration Modeling

Econometrics Toolbox provides Engle-Granger and Johansen methods for cointegration testing and modeling. The Engel-Granger method tests for individual cointegrating relationships and estimates their parameters. Johansen methods test for multiple cointegrating relationships and estimate parameters in corresponding vector error-correction (VEC) models. Johansen methods also test linear restrictions on error-correction speeds and the

space of cointegrating vectors, and they estimate restricted model parameters.

Volatility Modeling

Econometrics Toolbox has a complete set of tools for building on time-varying volatility models. The toolbox supports several variants of univariate GARCH models, including standard ARCH/GARCH models, as well as asymmetric EGARCH and GJR models designed to capture leverage effects in asset returns. The toolbox also

supports the simulation of stochastic volatility models.
