Análise de Componentes Principais: Resumo Teórico, Aplicação e Interpretação

Abstract

A análise multivariada de uma forma bem geral refere-se aos métodos estatísticos que analisam simultaneamente múltiplas medidas em cada indivíduo ou objeto sob investigação. Nesse contexto, entre as técnicas de multivariadas, a análise de componentes principais (ACP) é umas das técnicas estatísticas mais utilizadas na análise de dados em diversas áreas do conhecimento, como agronomia, zootecnia, ecologia, florestal, medicina, etc. Assim, discute-se neste artigo a aplicabilidade e a interpretação da análise de componentes principais e com utilização do gráfico biplot. Também, faz-se uma discussão quanto à escolha da metodologia mais adequada, levando em consideração a informação requerida e os objetivos do pesquisador.
