Sign Restricted SVAR in GAUSS
In structural vector autoregressive (SVAR) modeling, one of the core challenges is identifying the structural shocks that drive the system’s dynamics.
Traditional identification approaches often rely on short-run or long-run restrictions, which require strong theoretical assumptions about contemporaneous relationships or long-term behavior.
Sign restriction identification provides greater flexibility by allowing economists to specify only the direction, positive, negative, or neutral, of variable responses to shocks, based on theory.
In this blog, we’ll show you how to implement sign restriction identification using the new GAUSS procedure, **svarFit**, introduced in TSMT 4.0.

Estimating SVAR Models With GAUSS
Structural Vector Autoregressive (SVAR) models provide a structured approach to modeling dynamics and understanding the relationships between multiple time series variables. Their ability to capture complex interactions among multiple endogenous variables makes SVAR models fundamental tools in economics and finance. However, traditional software for estimating SVAR models has often been complicated, making analysis difficult to perform and interpret. In today’s blog, we present a step-by-step guide to using the new GAUSS procedure, svarFit, introduced in TSMT 4.0. We will cover: Estimating reduced form models. Structural identification using short-run restrictions. Structural identification using long-run restrictions. Structural identification using sign restrictions.

Why You Should Consider Constrained Maximum Likelihood MT (CMLMT)
The Constrained Maximum Likelihood (CML) library was one of the original constrained optimization tools in GAUSS. Like many GAUSS libraries, it was later updated to an “MT” version.
The “MT” version libraries, named for their use of multi-threading, provide significant performance improvements, greater flexibility, and a more intuitive parameter-handling system.
This blog post explores:
- The key features, differences, and benefits of upgrading from CML to CMLMT.
- A practical example to help you transition code from CML to CMLMT.
Exploring Categorical Data in GAUSS 25
Categorical data plays a key role in data analysis, offering a structured way to capture qualitative relationships. Before running any models, simply examining the distribution of categorical data can provide valuable insights into underlying patterns.
In GAUSS 25, these functions received significant enhancements, making them more powerful and user-friendly. In this post, we’ll explore these improvements and demonstrate their practical applications.
Whether summarizing survey responses or exploring demographic trends, fundamental statistical tools, such as frequency counts and tabulations, help reveal these patterns.
Making Your GAUSS Plots More Informative: Working with Legends
In data analysis, a well-designed graph can help clarify your insights but a poorly annotated one can confuse and distract your audience. That’s why proper annotation, including legends, is essential to creating effective graphs.
Legends play a crucial role in making graphs more readable by distinguishing between different groups, categories, or data series. A well-placed legend helps ensure that your message comes across clearly.
In this blog, we’ll walk through how to add and customize legends in GAUSS graphics.
