*
*In this workshop we will examine difference concepts related to quantiles, and practical issues based on R codes.

This workshop will present quantile regression, and the idea of iterative least square estimation. It will present an illustration on climate change and hurricanes.

### Learning Objectives

*The participant will:*

**1)**Basics on

**quantiles**: definition, use of quantiles for monte carlo simulation, boxplots, confidence intervals, etc.

**Present**

2)

2)

**quantile regression**and estimation issues. Application to hurricanes.

**Get an introduction of outliers, bagplot and**

3)

3)

**multivariate quantiles**

### Prerequisites

We will build on ideas presented in the workshop on Likelihood Methods, on least square regression.

The goal of this workshop is to present nice application of quantiles, and outlier detection.

That being said, a basic working understanding of R is assumed. Knowledge of functions and loops in R will be advantageous, but not a must. There will be connections at the end of the workshop with principal component analysis.
