Users often need a consistent look for their Stata graphs for publications or internal documents. To change one graph, the user can include options. To change many graphs at once, it is better to create a scheme or graph recording, which automates the changes and simplifies the graph commands. I...

Visualizing the true effect of a predictor over a range of values can be difficult for models that are not parameterized in their natural metric, such as for logistic or (even more so) probit models. Interaction terms in such models cause even more fogginess. In this talk, I show how both the...

Reproducible research is one of many names for the same concept: writing one report document that contains both the report and the commands from a statistical or programming language needed to produce the results and graphics contained in the report. It is called reproducible research because...

Reproducible research is one of many names for the same concept: writing a single report document that contains both the report and the commands needed to produce the results and graphics contained in the report. It is called reproducible research because any interested researcher can then...

There are many different ways to work in Stata depending on your desires: You can work using the menus, dialog boxes, Command window, or via the Do-file Editor. Stata 11 adds to this list with its new Variables Manager and much-improved Data Editor, both of which provide tools that make tasks...

One of Stata’s great strengths is its data management abilities. When either building or sharing datasets, some of the most time-consuming activities are validating the data and writing documentation for the data. Much of this futility could be avoided if datasets were self-contained, i.e., if...

Writing a document that contains statistical results in its narrative, including inline results, can take too much effort. Typically, users have a separate series of do-files whose results must then be pulled into the document. This is a very high-maintenance way to work in because updates to...

Visualizing interactions and response surfaces can be difficult. In this talk, I will show how to do the former by graphing adjusted means and the latter by showing how to roll together contour plots. I will demonstrate this for both linear and nonlinear models.
