estout, introduced by Jann (2005), is a useful tool for producing regression tables from stored estimates. However, its syntax is relatively complex and commands may turn out lengthy even for simple tables. Furthermore, having to store the estimates beforehand can be a bit cumbersome. To...

This paper describes the estimation of a general Blinder–Oaxaca decomposition of the mean outcome differential of linear and nonlinear regression models. Departing from this general model, we show how it can be applied to different models with discrete and limited dependent variables.

In this paper, we describe richness, a Stata program for the calculation of richness indices. Peichl, Schaefer, and Scheicher (2007) propose a new class of richness measures to contribute to the debate how to deal with the financing problems that European welfare states face as a result of...

This paper outlines a panel-data retrieval program written for Stata/SE or better, which allows easier accessing of the household panel datasets. Using a dropdown menu system, the researcher selects variables from any and all available years of the panel. The data are automatically retrieved and...

In this talk I describe three modes of Stata programming: authoring do-files, ado-files and Mata subroutines for ado-file programming. I discuss the advantages of developing skills in Stata programming that will help you become more efficient in your use of Stata and produce fully reproducible...

It is an often-encountered problem that variables of interest are scattered in different datasets. Given the two methodologically similar surveys, a question not asked in one survey could be seen as a special case of missing-data problem (Gelman et al., 1998). The paper presents a model for...

Extreme data are known to be highly influential when measuring income inequality from microdata. Similarly, Lorenz curves and dominance criteria are sensitive to data contamination in the tails of the distribution. In this presentation, I intend to introduce a set of user-written packages that...

This paper describes the estimation of the parameters of a double-hurdle model in Stata. It is shown that the independent double-hurdle model can be estimated using a combination of existing commands. Likelihood evaluators to be used with Stata’s ml facilities are derived to illustrate how to...

PanelWhiz plugins are modular data-cleaning programs for specific items in PanelWhiz. Each plugin is designed to recode, deflate, and change existing variables being extracted in a panel-data retrieval. Furthermore, new variables can be generated on the fly. The PanelWhiz plugin system is a...

With longer follow-up times, the proportional hazards assumption is questionable in the Cox model. Cox suggested to include an interaction between a covariate and a function of time. To estimate such a function in Stata, a substantial enlargement of the data is required. This may cause severe...
