The purpose of this talk is to illustrate the main features and applications of two new Stata programs for spatial density estimation: spgrid and spkde. The spgrid program generates two-dimensional arrays of evenly spaced points spanning across any regular or irregular study region specified by...

In this talk, I will present the basic principles of exploratory spatial data analysis and their application using Stata. After a brief discussion of the specific features of spatial data, I will show some freely-available user-written Stata commands (spmap, spgrid, spkde, spatwmat, spatgsa,...

Sometimes social scientists are interested in determining whether, and to what extent, the distribution of a given variable of interest Y varies across the categories of a second variable D. When the number of valid observations within one or more categories of D is small and/or collected data...

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...
