# Statistics III

## Objectives

This course unit aims to extend the knowledge acquired in Statistics II, as well as provide students with theoretical and practical knowledge concerning nonparametric statistical inference methodologies. The syllabus of the course comprises instruments nonparametric statistical inference as orders, statistics, order statistics, the estimators and sampling distributions, estimation nonparametric point and interval hypothesis tests and nonparametric. Are treated equally essential aspects of asymptotic distributions. The students should get to know the estimators and their properties, to construct confidence intervals and nonparametric testing of nonparametric hypotheses. For each non-parametric procedure, students should know clearly its applicability conditions.
