This book describes how to use test equating methods in practice. The non-commercial software R is used throughout the book to illustrate how to perform different equating methods when scores data are collected under different data collection designs, such as equivalent groups design, single group design, counterbalanced design and non equivalent groups with anchor test design. The R packages equate, kequate and SNSequate, among others, are used to practically illustrate the different methods, while simulated and real data sets illustrate how the methods are conducted with the program R. The book covers traditional equating methods including, mean and linear equating, frequency estimation equating and chain equating, as well as modern equating methods such as kernel equating, local equating and combinations of these. It also offers chapters on observed and true score item response theory equating and discusses recent developments within the equating field. More specifically it covers the issue of including covariates within the equating process, the use of different kernels and ways of selecting bandwidths in kernel equating, and the Bayesian nonparametric estimation of equating functions. It also illustrates how to evaluate equating in practice using simulation and different equating specific measures such as the standard error of equating, percent relative error, different that matters and others.

Quantitative Psychology

In this wordless graphic novel, Captain Barbosa sails the seven seas with his trusty shipmates: a fly, an alligator, and an elephant. A seagull steals his treasured hat, and Barbosa and his crew give chase through a nasty storm. When Barbosa reaches the seagull's island, he finds the hat—along with a nest of baby seagulls—and decides even pirates can forgive and forget.

El pecado de El “Rucio”. Las claves del crimen de Hans Pozo (Editorial Catalonia), obra de los periodistas de la Universidad Católica Daniel Halpern, Jorge González y Pablo Unda, ha logrado el halago de la crítica. Para muchos, este libro escapa a su género y se asemeja a un perfecto relato de ficción policial. Otros declaran que su lectura es apasionante y adictiva hasta la última página. Sumado a sus aciertos de estilo y literarios, El pecado de El Rucio, abre una reflexión sobre la necesidad de que en Chile se potencie la investigación periodística, pues son cada vez menos los profesionales que están dispuestos a invertir tiempo y esfuerzos en este género. Durante más de un año los autores con el apoyo de otros tres periodistas investigaron la historia del llamado descuartizado de Puente Alto. Entrevistaron a los protagonistas y tuvieron acceso a los expedientes del caso. Entraron a las poblaciones y convivieron con la marginalidad y la pobreza. Todo para recrear uno de los crímenes más impactantes de la historia policial chilena. A través del fiscal Pablo Sabaj conocieron el operar de la Reforma Procesal Penal y fueron testigos de los conflictos entre Carabineros e Investigaciones por alcanzar mayor protagonismo en pos de resolver el mediático caso. Para Halpern, González y Unda la investigación constituye un aporte que va más allá de los datos inéditos que revela sobre el crimen. A través del desarrollo del libro se hace evidente que la marginalidad, la droga y la falta de oportunidades inciden en los destinos de muchos jóvenes chilenos.
