It is assumed that you have had at least a one quarter/semester course in regression (linear models) or a general statistical methods course that covers simple and multiple regression and have access to a regression textbook that explains the theoretical background of the materials covered in these chapters.

Bons exemplos de análises complexas com vários softwares

The pages below contain examples (often hypothetical) illustrating the application of different statistical analysis techniques using different statistical packages. Each page provides a handful of examples of when the analysis might be used along with sample data, an example analysis and an explanation of the output, followed by references for more information. These pages merely introduce the essence of the technique and do not provide a comprehensive description of how to use it.

Raynald’s SPSS tools

Páginas pessoais com muita info. sobre SPSS

Desde Dezembro de 1998 que tenho participado no grupo de discussão SPSSX-L e no newsgroup comp.soft-sys.stat.spss. Estas participações aumentaram o meu grau de conhecimento acerca SPSS em cerca de 25. Tenho aprendido muito com muitos utilizadores do SPSS, tais como:

John Hendrickx, Hector E. Maletta, Rolf Kjoeller, David Marso e Neila Nessa.

Pelo meu lado, respondi a cerca de 2100 questões colocadas nestes dois grupos de discussão. É mais divertido aprender o SPSS através da resposta a questões reais, do que a ler livros e a “inventar problemas” para resolver. Acho que a diversidade de problemas e situações com que nos deparamos nestes grupos fascinantes. (E isto, provavelmente, diz muita coisa acerca da minha personalidade ).

Para uma visão geral da minha página, queiram consultar o mapa do site.

SPSS Programming and Data Management book

Posted by Armando Brito Mendes | Filed under estatística, software

Manual grátis do IBM-SPSS

SPSS Programming and Data Management:
A Guide for SPSS and SAS Users

The first edition of the book was released by SPSS on January 7th, 2004. Here is the description found on SPSS’s site:

SPSS is pleased to announce the availability of “SPSS Programming and Data Management: A Guide for SPSS and SAS Users” written by SPSSX list member, Raynald Levesque, already well known for his practical solutions to complex SPSS programming problems.

The book reveals the wealth of functionality beneath the SPSS graphical user interface, with detailed examples of command syntax, the macro facility, scripting, and the new Output Management System. Until now, no other book has focused on these features, and many users have been unaware of the data management power and flexibility available in SPSS. The book also contains a chapter for users familiar with SAS, demonstrating how many common data management tasks are performed in both SAS and SPSS.

Although the first 5 editions (for SPSS 12 to SPSS 16) were available in hard copy, this is no longer the case. Only pdf versions are available for SPSS 17 and newer.

OrgOrgChart: The Evolution of an Organization

Posted by Armando Brito Mendes | Filed under planeamento, videos, visualização

As empresas são organismos vivos: animação do organigrama de uma grande empresa

The OrgOrgChart (Organic Organization Chart) project looks at the evolution of a company’s structure over time. A snapshot of the Autodesk organizational hierarchy was taken each day between May 2007 and June 2011, a span of 1498 days.

Each day the entire hierarchy of the company is constructed as a tree with each employee represented by a circle, and a line connecting each employee with his or her manager. Larger circles represent managers with more employees working under them. The tree is then laid out using a force-directed layout algorithm.

Each second in the animation is about one week of activity, and acquisitions are most obvious when big clumps of people join the company. The long-term changes are a little harder to see, because the branches in the network fade into the background. Recomputing the layout each week might be good for the next round.
