Introduction We use regression analysis to understand the relationships, patterns, and causalities in data. Often we are interested in understanding the impacts that changes in the dependent variables have on our outcome of interest. Marginal effects measure the impact that an instantaneous unit change in one variable has on the outcome variable while all other [...]
Learn how the GAUSS element-by-element conformability rules help you to create code which is compact, elegant and fast! Applies to functions as well as matrices and vectors. Avoids the need for loops in many cases. Important concepts to help you get the most from GAUSS. Next: GAUSS Basics 6: Logical and relational operators Previous: GAUSS [...]
Introduction In this blog, we examine one of the fundamentals of panel data analysis, the one-way error component model. Today we will: Explain the theoretical one-way error component model. Consider fixed effects vs. random effects. Estimate models using an empirical example. The theoretical one-way error component model The one-way error-component model is a panel data [...]
This fourth video in our GAUSS Basics series will explain how to perform: Matrix operations. Element-by-element operations on matrices. Next: GAUSS Basics 5: Element-by-element conformability Previous: GAUSS Basics 3: Introduction to matrices
Introduction When policy changes or treatments are imposed on people, it is common and reasonable to ask how those people have been impacted. This is a more difficult question than it seems at first glance. In order to truly know how those individuals have been impacted, we need to consider how those individuals would be [...]
This third video in our GAUSS Basics series will show you how to: Create matrices. Find their size. Access specific elements with indexing. Grow them with matrix concatenation. Next: GAUSS Basics 4: Matrix operations Previous: GAUSS Basics 2: Running a program
Introduction GAUSS includes a plethora of tools for creating publication-quality graphics. Unfortunately, many people fail to use these tools to their full potential. Today we unlock five advanced GAUSS hacks for building beautiful graphics: Using HSL, HSLuv, and Colorbrewer color palettes. Controlling graph exports. Changing the plot canvas size. Annotating graphs with shapes, text boxes, [...]
This second video in our new GAUSS Basics series will show you how to: Create and run a GAUSS program. Use recommended file extensions. Create and print strings. Add code comments. Next: GAUSS Basics 3: Introduction to matrices Previous: GAUSS Basics 1: Interactive commands
This is the first video in our new GAUSS Basics series. This series is designed to teach you everything you need to know to be productive with GAUSS. This video is designed to be your first step in GAUSS! Learn how to: Create variables. Use arithmetic operators. Enter interactive commands. View the variables in your [...]
Introduction In this blog, we extend last week's analysis of unit root testing with structural breaks to panel data. We will again use the quarterly current account to GDP ratio but focus on a panel of data from five countries: United States, United Kingdom, Australia, South Africa, and India. Using panel data unit roots tests [...]
