High-dimensional statistics: Theory and practice
Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Main themes
The course focuses on high-dimensional settings and on techniques to that
allow parameter estimation for high-dimensional models in statistics.
Aims

At the end of this learning unit, the student is able to :

1 A. Eu égard au référentiel AA du programme de master en statistique, orientation générale, cette activité contribue au développement et à l'acquisition des AA suivants, de manière prioritaire : 1.4, 1.5, 2.4, 4.3, 6.1, 6.2.
B. By the end of this class, the student will be able to understand the basic
concepts of penalized estimation and will be able to apply these concepts to
perform estimation/inference for high-dimensional models in statistics.
