          Abstract

          Sisvar is a statistical analysis system with a large usage by the scientific community to produce statistical analyses and to produce scientific results and conclusions. The large use of the statistical procedures of Sisvar by the scientific community is due to it being accurate, precise, simple and robust. With many options of analysis, Sisvar has a not so largely used analysis that is the multiple comparison procedures using bootstrap approaches. This paper aims to review this subject and to show some advantages of using Sisvar to perform such analysis to compare treatments means. Tests like Dunnett, Tukey, Student-Newman-Keuls and Scott-Knott are performed alternatively by bootstrap methods and show greater power and better controls of experimentwise type I error rates under non-normal, asymmetric, platykurtic or leptokurtic distributions.

          O Sisvar é um sistema de analise estatística de amplo uso pela comunidade científica para realização de suas análises estatísticas e, portanto, para produção de seus resultados científicos e realização de suas descobertas. O grande uso dos procedimentos de analises estatísticas do, Sisvar pela comunidade científica ocorre em virtude de ter acurácia, precisão simplicidade e robustez. Dentro de tantas opções de analises, o Sisvar tem uma ferramenta não muito usada, que são os procedimentos de comparações múltiplas, usando as aproximações bootstrap. Neste artigo, objetivou-se revisar esse assunto e mostrar algumas vantagens em se utilizar o Sisvar para realizer tal análise na comparação das médias de tratamentos. Testes como os de Dunnett, Tukey, Student-Newman-Keuls e Scott-Knott são aplicados alternativamente por meio de métodos bootstrap e mostram elevado poder e melhor controle das taxas de erro tipo I por experimento sob distribuições não-normais, assimétricas, platicúrticas ou leptocúrticas.

          An Introduction to the Bootstrap

          Statistics is a subject of many uses and surprisingly few effective practitioners. The traditional road to statistical knowledge is blocked, for most, by a formidable wall of mathematics. The approach in An Introduction to the Bootstrap avoids that wall. It arms scientists and engineers, as well as statisticians, with the computational techniques they need to analyze and understand complicated data sets.
