8. Regression Analysis
Regression analysis is fundamental in financial econometrics. Gretl supports multiple
types of regression, including:
❑ Ordinary Least Squares (OLS) Regression: For modeling the relationship between
a dependent variable and one or more independent variables.
❑ Logistic Regression: Useful for binary outcome variables, such as predicting
market upturns or downturns.
❑ Quantile Regression: Helps understand the impact of variables across different
quantiles of the dependent variable, often used in risk management.

9. Time Series Analysis
Financial data is often time-dependent. Gretl excels in time series analysis with
features like:
❑ Autoregressive Integrated Moving Average (ARIMA) Models: For modeling and
forecasting time series data.
❑ Vector Autoregression (VAR): Useful for analyzing the dynamic impact of multiple
time series on each other.
❑ Cointegration Tests: To identify long-term equilibrium relationships between
time series variables.

10. Volatility Modeling
Understanding and predicting volatility is crucial in financial markets.
Gretl supports Generalized Autoregressive Conditional
Heteroskedasticity (GARCH) models, which are widely used to model
financial time series with varying volatility.

Gretl provides a range of hypothesis tests, including:
❑ Unit Root Tests: To check for stationarity in time series data.
❑ Granger Causality Tests: To determine if one time series can
predict another.
❑ Wald Tests: For testing the significance of coefficients in a
regression model.
