Model and analyze financial and economic systems using statistical methods
Econometrics Toolbox™ provides functions for modeling economic data. You can lect and calibrate economic models for simulation and forecasting. For time ries modeling and analysis, the toolbox includes univariate ARMAX/GARCH composite models with veral 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 u a variety of diagnostic functions for model lection, including hypothesis, unit root, and stationarity tests.
Key Features

Model Identification and Analysis
With Econometrics Toolbox, you can lect 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 the analys, including:
▪Likelihood ratio, Wald, and Lagrange multiplier tests for model specification
▪Akaike and Bayesian information criteria for model order lection
▪Engle’s test for the prence of ARCH/GARCH effects
▪Sample autocorrelation, cross-correlation, and partial autocorrelation functions
▪Ljung-Box Q (portmanteau) test for autocorrelation

State-Space Modeling and Parameter Estimation
Econometrics Toolbox includes functions for creating state-space models and tools for estimating parameters bad on the 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 ts or data ts with missing data using the Kalman filter.
