Review of Alan Acock's a Gentle Introduction to Stata, Fourth Edition

A gentle introduction to

The PythonTEX package allows authors to combine computational and typesetting tasks by embedding Python code in TEX documents. This package allows access to many powerful Python modules, providing support for such things as symbolic mathematics, plotting, arbitrary precision numerical calculations, and networking. Python’s intuitive syntax, popularity, and extensibility along with TEX’s formatt...

Review: a gentle introduction to imputation of missing values.

In most situations, simple techniques for handling missing data (such as complete case analysis, overall mean imputation, and the missing-indicator method) produce biased results, whereas imputation techniques yield valid results without complicating the analysis once the imputations are carried out. Imputation techniques are based on the idea that any subject in a study sample can be replaced ...

A Gentle Introduction to Tensors

A Gentle Introduction to Globus

As computers become better connected across the globe, opportunities to create new programs utilizing geographically distant resources increase. New applications not possible without this computational grid include distributed supercomputing and intelligent sensing applications. However, di culties implementing this new class of applications exist: the computers on a grid are unreliably connect...

A Gentle Introduction to NUMERICA

NUMERICA is a modeling language for stating and solving global optimization problems. It makes it possible to express these problems in a notation close to the way these problems are stated in textbooks or scientific papers. In addition, the constraint-solving algorithm of NUMERICA, which combines techniques from numerical analysis and artificial intelligence, provides many guarantees about cor...
