The glcurve command is updated to a Stata 7 version, glcurve7, which is described and illustrated. Copyright 2001 by Stata Corporation.

In this article, we describe an implementation of a space-filling locationselection algorithm. The objective is to select a subset from a list of locations so that the spatial coverage of the locations by the selected subset is optimized according to a geometric criterion. Such an algorithm...

This insert describes the module akdensity. akdensity extends the official kdensity that estimates density functions by the kernel method. The extensions are of two types: akdensity allows the use of an "adaptive kernel" approach with varying, rather than fixed, bandwidths; and akdensity...

In this article, I describe estimation of the kernel-smoothed cumulative distribution function with the user-written package akdensity, with formulas and an example.

We discuss methods for calculating multivariate normal probabilities by simulation and two new Stata programs for this purpose: mdraws for deriving draws from the standard uniform density using either Halton or pseudorandom sequences, and an egen function, mvnp(), for calculating the...

We discuss the application of the GHK simulation method for maximum likelihood estimation of the multivariate probit regression model and describe and illustrate a Stata program mvprobit for this purpose. Copyright 2003 by StataCorp LP.
