Genetic association studies often explore the relationship between diseases and collections of contiguous genetic markers located on the same chromosome known as haplotypes. Haplotypes are usually not observed directly but are inferred statistically using a variety of algorithms. One of the most...

In this presentation we define two qualitatitive response models: 1) Selection Endogenous Dummy Ordered Probit model (SED-OP); 2) a Selection Endogenous Dummy Dynamic Selection Ordered Probit model (SED- DOP). The SED-OP model is a three-equation model constituted of an endogenous dummy...

This short talk describes the module -dsginideco- which decomposes the change in income inequality between two time periods into two components, one representing the progressivity (pro-poorness) of income growth, and the other representing reranking. Inequality is measured using the generalized...

I have researched the economics of interactions on Statalist, based on the full population of exchanges from 1st of January to 30th of April 2009. Both the "demand side" - the questions asked on the list - and the "supply side" - the answers provided - are examined. Along the way, I have paid...

Circular statistics are needed when one or more variables have outcome space the circle, which is for example true for data measured with reference to compass, clock or calendar. Applications abound in the Earth and environmental sciences, not to mention economic and medical fields well...

The tutorial will show how results from various Stata commands can be processed efficiently for inclusion in customized reports. A two-step procedure is proposed in which results are gathered and archived in the first step and then tabulated in the second step. Such an approach disentangles the...

In many research studies, respondents' beliefs and opinions about various concepts are often measured by means of five, six and seven point scales. The widely used five point scale is commonly known as a Likert scale (Likert, (1932) "A technique for the measurement of attitudes", Archives of...

This tutorial aims to cover many of the aspects of the flexible parametric alternatives to the Cox model that we have been developing.
