In this presentation, the author presents a procedure and an illustrative application of a user-written Allocation Model(AE) in Stata. AE measures allocative efficiency and economic efficiency as well as technical efficiency when price and cost information of production are available. This model...

In this presentation, we present a procedure and an illustrative application of user-written mathematical optimization programs-Linear Programming(LP) and Mixed Integer Linear Programming(MILP). The LP and MILP programs in Stata will allow researchers to easily access the Stata system and to...

In this presentation, the author presents a procedure and an illustrative application of a user-written Malmquist Productivity Analysis(MPA) using Data Envelopment Analysis (DEA) frontier in Stata. MPA measures the productivity changes for units between time periods. MPA has been used widely for...

Korea government initiated the Government's Defense Industrial Policy, "Defense Industry as a New Growth Engine for the Creative Economy", followed by establishing the defense industrial policy objectives and making efforts to reach them. Accordingly, the defense export dragged attention from...

In this article, we introduce a user-written data envelopment analysis command for Stata. Data envelopment analysis is a linear programming method for assessing the efficiency and productivity of units called decision-making units. Over the last decades, data envelopment analysis has gained...

In October 2012 HarvardX, through edX, offered its first two online courses. One of these was called PH207X: Health in Numbers. The course covered biostatistics and epidemiology at an introductory level and lasted 12 weeks. 60,000 students later we had exposed more students to those disciplines...

binscatter is a newly released program that produces binned scatterplots, which provide a non-parametric estimate of a conditional expectation function. This presentation will describe the features of binscatter, and explore its versatile applications. Those applications include: observing the...

Many estimation problems focus on classification of cases (into bins) with tools that aim to identify cases using only a small subset of all possible questions. These tools can be used in diagnoses of disease, identification of advanced or failing students using tests, or classification into...

The last three years have seen explosive growth in the variety and sophistication of interactive online graphics. These are mostly implemented in the web language JavaScript, with the D3 (Data Driven Documents) library being the most popular and flexible at present. Leaflet is a mapping library...
