Abstract

Neste trabalho é aplicada a meta heurística Otimização por Enxame de Partículas (Particle Swarm Optimization -PSO) na identificação de pontos influentes. Estes pontos exercem grande influência na determinação dos coeficientes do modelo de regressão. Foi utilizada, como função objetivo, a função de sensibilidade de casos gCook(ǫ) que tem comportamento multimodal. A eficiência da metodologia proposta foi testada em conjuntos de dados simulados. Os resultados obtidos mostram que esta metodologia apresenta soluções satisfatórias na identificação de pontos influentes.
