Abstract

Este es material de curso para un curso introductorio a la Probabilidad y la Estadistica en Ingenieria y Administracion. Es parte de algunas notas de clases de mis cursos en Espanol sobre esos temas. Cuando se toman decisiones y existen eventos futuros y desconocidos la unica razon por la cual el tomador de decisiones se equivoca es por algun error en su analisis. Esto se conoce como toma de decisiones bajo incertidumbre. En esta nota se presentan las herramientas basicas para el analisis de regresion. Con el analisis de regresion lineal es posible encontrar modelos que relacionan variables con una causalidad entre ellas. La idea es usar esta herramienta para predecir el comportamiento de algunas variables independientes y otras dependientes. Antes de hacer cualquier analisis estadistico se debe examinar si existe una relacion logica entre las variables independientes y dependientes. Los calculos se hacen facilmente usando el poco costos poder de computacion de los software y computadores. Hallar una posible relacion entre variables es una delicada labor de observacion, inteligencia, experiencia e intuicion. Todos estos metodos son estudiados usando intensivamente hojas de calculo.
