# Multivariate Statistics

## Objectives

It is intended to familiarize the student with inference techniques for multivariate mean values and covariance matrices, as well as multivariate linear models in Gaussian populations, dimensionality reduction methods, discrimination and data classification methods.

### Teaching method

`Lectures will be presential (if possible, to be confirmed). `

`It is intended that the classes work according to an essentially interactive teaching model, `

using practical exercise resolution and data analysis in R environment.

### Evaluation method

**Continuous evaluation:**

It includes the following components:

*1st test*(MT1) - Test with a weight of 30%. The test will have a time limit of 2 hours. The test is rated on a scale of 0 to 20 points (with a minimum rating of 7).*2nd test*(MT2) - Test with a weight of 30%. The test will have a time limit of 2 hours. The test is rated on a scale of 0 to 20 points (with a minimum rating of 7).*Work/Report*(T) - Individual work, with a weight of 40%, rated on a scale of 0 to 20 values. This work has to be turned in between November 27 and December 4.

Final grade calculation formula (NF): NF = 0.3 x MT1+ 0.3 x MT2 + 0.4 x T (partial grades rounded to the nearest unit)

**Resource (Improvement)/Special**: In-person written test, to be held on a single date, within the period provided for in the academic calendar, with a weight of 100%. The exam will have the duration of 3 hours. Rated on a scale from 0 to 20 points.
