Planning Experiments with Nonlinear Models
The main objective of this course is to explore Design of Experiments with Nonlinear Models,we initially fit the student in the area of linear and nonlinear modeling, to review basic knowledge. Assumptions and methods of model linearization are addressed. Then we introduce the notion of Locally Optimal Plans by exploring Optimization criteria, illustrating the canonical form and some geometric aspects of the models. Static Plans are studied under different approaches and using the Maximin criterion. Sequential Plans and Approximate Confidence Regions are explored, concluding the UC with the experimental part, presenting several examples and their computation using the R software. The student will also be provided with contact with the analysis and validation methodologies of the estimated models, by comparison with the theoretical assumptions.

E-learning
Evaluation is made on individual basis and it involves the coexistence of two modes: continuous assessment (at least 60%) and final evaluation (at most 40%). Further information is detailed in the Learning Agreement of the course unit.
