#### Remark

Course given every two years

#### Summary

A second course on regression modelling, dealing with nonlinear effects of explanatory variables, and non-normal and dependent response variables.

#### Content

Revision of linear regession and likelihood inference

Fitting algorithms for nonlinear models and related diagnostics

Generalised linear model; exponential families; variance and link functions

Proportion and binary responses; logistic regession

Count data and Poisson responses; log-linear models

Overdispersion and quasilikelihood; estimating functions

Mixed models, random effects, generalised additive models and penalized regression

#### Keywords

Binary response; Count data; Deviance; EM algorithm; Estimating function; Iterative weighted least squares algorithm; Lasso; Likelihood; Logistic regression; Longitudinal data; Mixed model; Multinomial distribution; Overdispersion; Poisson distribution; Quasi-likelihood; Random effects

#### Learning Prerequisites

##### Required courses

Knowledge of basic probability and statistics, at, for example, the levels of MATH-240 and MATH-230

Linear models (MATH-341) or equivalent

##### Important concepts to start the course

Linear regression; likelihood inference; R

#### Learning Outcomes

By the end of the course, the student must be able to:
• Develop theoretical elements needed in regression analysis
• Apply the statistical package R to the analysis of data
• Assess / Evaluate the quality of a model fitted to regression data, and suggest improvements
• Choose a suitable regression model

#### Transversal skills

• Demonstrate a capacity for creativity.
• Demonstrate the capacity for critical thinking
• Write a scientific or technical report.

#### Teaching methods

Ex cathedra lectures; homework both theoretical and practical; mini-project

#### Expected student activities

Attending lectures; solving theoretical problems; solving applied problems using statistical software

#### Assessment methods

Written final exam; mini-project

Dans le cas de l'art. 3 al. 5 du Règlement de section, l'enseignant décide de la forme de l'examen qu'il communique aux étudiants concernés.
