- 7. Descriptive Statistics Gretl provides tools to compute descriptive statistics, such as mean, median, standard deviation, skewness, and kurtosis, offering a preliminary understanding of the financial data's characteristics. 7 www.statisticshelpdesk.com
- 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. 8 www.statisticshelpdesk.com
- 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. 9 www.statisticshelpdesk.com
- 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. 10 www.statisticshelpdesk.com
- 11. Hypothesis Testing 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. 11 www.statisticshelpdesk.com
