A Stata Plugin for Estimating Group-Based Trajectory Models

Group-based trajectory models are used to investigate population differences in the developmental courses of behaviors or outcomes . This article demonstrates a new Stata command, traj, for fitting to longitudinal data finite (discrete) mixture models designed to identify clusters of individuals following similar progressions of some behavior or outcome over age or time. Censored normal, Poisso...

Censored Quantile Instrumental Variable Estimation with Stata

Many applications involve a censored dependent variable and an endogenous independent variable. Chernozhukov et al. (2015) introduced a censored quantile instrumental variable estimator (CQIV) for use in those applications, which has been applied by Kowalski (2016), among others. In this article, we introduce a Stata command, cqiv, that simplifes application of the CQIV estimator in Stata. We s...

Constructing Diagrams Representing Group Motions

Certain domains, such as military activities and weather phenomena, are characterized by a large number of individual elements moving in a field, either in pursuit of an organized activity in groups at different levels of aggregation (military action), or subject to underlying physical forces that cluster different elements in different groups with common motion (weather). Reasoning about pheno...

Constructing a Configurable Group RPC Service

Current Remote Procedure Call (RPC) services implement a variety of semantics, with many of the differences related to how communication and server failures are handled. The list increases even more when considering group RPC, a variant of RPC often used for fault-tolerance where an invocation is sent to a group of servers rather than one. This paper presents an approach to constructing group R...

Constructing Weyl Group Multiple Dirichlet

Let Φ be a reduced root system of rank r. A Weyl group multiple Dirichlet series for Φ is a Dirichlet series in r complex variables s1, . . . , sr, initially converging for Re(si) sufficiently large, that has meromorphic continuation to C and satisfies functional equations under the transformations of C corresponding to the Weyl group of Φ. A heuristic definition of such series was given in [2]...
