Learning objectives

 

Referring to knowledge

The main objective of the course is to understand linear models and their application to the most common situations:

— Know the processes of parameter estimation in a linear model.

— Know the decision-making mechanisms associated with the main hypothesis tests in linear models.

— Know how to characterize a simple and multiple linear regression model.

— Know how to validate linear regression models.

— Know how to characterize some simple models of variance analysis.

 

Referring to abilities, skills

— Know how to solve the parameter estimation of a linear model.

— Know how to analyse the main hypothesis tests in linear models.

— Know how to validate a linear regression model.

— Know how to validate a linear regression model.

— Know how to solve some simple models of variance analysis.

— Be able to interpret the results rigorously.
