| Main themes |
1) Aims of the course, means, support, evaluation. Reminder: bases of statistical inference.
2) Analysis of variance (1, 2 and 3 way): principle, models, tests, comparison of means, concepts of interaction, nesting, fixed or random factor levels.
3) Correlation, simple and multiple linear regression: model, estimation, inference, prediction, model selection with AIC.
4) Analysis of count data: fitting a probability law, two- and three-way contingency tables.
5) Introduction to generalized linear models.
6) Non parametric methods
The theoretical lectures and practical works shall rely upon real cases. Practical works will be realized using computer software.
|
| Aims |
The student shall understand, and become able to use correctly and critically the principal methods for the statistical analysis of biological and environmental univariate data. He perceives the relationship between experimental design and analysis model and the necessity of planning experiments, and becomes familiar with computer-aided data analysis.
After completing this course, the student should master the basic methods for the analysis of univariate data, be able to choose the analysis model and method adapted to the design of simple factorial experiments, to analyse and interpret correctly the results of such experiments. He should be able to progress by himself and follow fruitfully advanced lectures on experimental design and data analysis.

| Content |
1) Aims of the course, means, support, evaluation. Reminder: bases of statistical inference.
2) Analysis of count data: fitting a probability law, two- and three-way contingency tables (homogeneity tests, independence: marginal, partial, conditional).
3) Simple linear regression: model, estimation, inference, validation, prediction.
4) Multiple regression: modelling the effects, model and design, F-tests and AIC criterion; model selection.
5) One-way analysis of variance: principle, models, tests, comparison of means.
6) Multiple-way Anova: concepts of interaction, nesting, fixed or random factor levels, some designs for heterogeneity control.
7) "What next?" Some indications related to the interests of the students (e.g. linear and non linear modelling, non parametric methods, multivariate analysis, geostatistics, Monte-Carlo methods
).
