Using the approach proposed in 2002 by the Technical Committee for the Measurement of Poverty (TCMP), CONEVAL produced a set of state-level poverty measures. The methodology consists of comparing a food basket that contains the minimum consumption requirements with a household’s average...

In this talk, I will cover a number of topics related to the estimation of panel models for count data, with empirical illustrations estimated using Stata. For the theoretical background, I will rely on my book with Colin Cameron, Microeconometrics: Methods and Applications (2005, Cambridge...

In this presentation, we illustrate an application of a relatively new selection-bias correction methodology based on the multinomial logit model using the selmlog Stata command (Bourguignon, Fournier, and Gurgand, 2007, Journal of Economic Surveys 21: 174–205). selmlog allows for getting both...

In biology, the study of the life cycle of plants and animals helps one to understand the phenology of a particular species, which is useful in pest management or in biological conservation. Spiders are one of the most widespread animals on earth. They eat a huge variety of other animals and are...

In 2009, CONEVAL (Consejo Nacional de Evaluación de la Política de Desarrollo Social) presented the official methodology to measure multidimensional poverty in Mexico, which is a set of intuitive indicators that measure income and social rights deprivation, taking into account the territorial...

This presentation is a tutorial on how to analyze complex survey data in Stata. I will start by reviewing the sampling methods most frequently used for survey data and examining why a special treatment is needed to perform estimations using these data. I will discuss the concepts of...

The creation and testing of interaction terms in regression models can be very cumbersome, even in Stata 8. We propose a simple wrapping command, -fitint-, that fits any generalised linear model and tests any twoway interactions, as well as all main effects. There is no need to use -xi- because...

Among various structures in Stata for cycling through lists (whether lists of variable names, numbers, or arbitrary strings) are foreach and forvalues, introduced in Stata 7 in 2001, and for, introduced in Stata 3.1 in 1992, and revised in 5.0 (1997) and 6.0 (1999). Typically, each member of the...

I research the market efficiency of the German 6/49 parimutuel lottery game using Stata. To this end, I investigate the existence of profit opportunities for particularly unpopular combinations of numbers (Papachristou and Karamanis (1998)), employing the covariates proposed by Henze and Riedwyl...

A Stata program will be presented for improved quality control of econometric models. It is well known that reported econometric results often have unknown reliability because of selective reporting by the researcher. In particular, t-statistics are often uninformative or misleading when...
