Visualizing COVID-19 Panel Data With GAUSS 22

When they’re done right, graphs are a useful tool for telling compelling data stories and supporting data models. However, too often graphs lack the right components to truly enhance understanding. In this blog, we look at how a few quick customizations help make graphs more impactful. In particular, we will consider:

Using grid lines without cluttering a graph.
Changing tick labels for readability.
Using clear axis labels.
Marking events and outcomes with lines, bars, and annotations.

Getting to Know Your Data With GAUSS 22

There is no getting around the fact that data wrangling, cleaning, and exploring plays an important role in any empirical research. Data management can be time-consuming, error-prone, and can make or break results. GAUSS 22 is built to take the pain out of dealing with your data and to let you move seamlessly towards tackling your important research questions. In today’s blog, we walk through how to efficiently prepare and explore real-world data before modeling or estimation. We’ll look at:

Loading and merging data.
Cleaning data to eliminate misentries, missing values, and more.
Exploring data.

The Quantile Autoregressive-Distributed Lag Parameter Estimation and Interpretation in GAUSS

The QARDL model has grown increasingly popular in time series analysis. It is a convenient model for addressing autocorrelation, disentangling long-term and short-term relationships, and addressing asymmetric relationships. In today’s blog, we look at the basics of the QARDL model including:

The intuition behind the QARDL model.
How to estimate the QARDL model in GAUSS.
How to interpret the QARDL results.

The Structural VAR Model at Work: Analyzing Monetary Policy

In today’s blog, we put the building blocks of the structural vector autoregressive (SVAR) model to work in a practical application. We’ll use one of the most common applications of SVAR models, monetary policy analysis, to see the SVAR in action. After this blog, you should have a stronger understanding of:

How to use Granger causality testing to inform model selection.
How to implement short-run identification restrictions.
How to conduct and interpret structural VAR analysis.
