What statistical analysis should I use?
Posted by Armando Brito Mendes | Filed under estatística, software
Excelente tabela de decisão sobre os métodos estatísticos com exemplos
The following table shows general guidelines for choosing a statistical analysis. We emphasize that these are general guidelines and should not be construed as hard and fast rules. Usually your data could be analyzed in multiple ways, each of which could yield legitimate answers. The table below covers a number of common analyses and helps you choose among them based on the number of dependent variables (sometimes referred to as outcome variables), the nature of your independent variables (sometimes referred to as predictors). You also want to consider the nature of your dependent variable, namely whether it is an interval variable, ordinal or categorical variable, and whether it is normally distributed (see What is the difference between categorical, ordinal and interval variables? for more information on this). The table then shows one or more statistical tests commonly used given these types of variables (but not necessarily the only type of test that could be used) and links showing how to do such tests using SAS, Stata and SPSS.

Bom livro sobre regressão linear com SPSS
by Xiao Chen, Phil Ender, Michael Mitchell and Christine Wells (in alphabetical order) The aim of these materials is to help you increase your skills in using regression analysis with SPSS. This web book does not teach regression, per se, but focuses on how to perform regression analyses using SPSS. 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.
