401-4597-67L | Probability on Transitive Graphs | W | 4 credits | 2V | V. Tassion | |

Abstract | In this course, we will present modern topics at the interface between probability and geometric group theory. We will define two random processes on Cayley graphs: the simple random walk and percolation, and discuss their respective behaviors depending on the geometric properties of the underlying group. | |||||

Objective | Present in an original framework important tools in the study of - random walks: spectral gap, harmonic functions, entropy,... - percolation: uniqueness of the infinite cluster, mass-transport principle,... | |||||

Content | In this course, we will present modern topics at the interface between probability and geometric group theory. To every group with a finite generating set, one can associate a graph, called Cayley graph. (For example, the d-dimensional grid is a Cayley graph associated to the group Z^d.) Then, we will define two random processes on Cayley graphs: the simple random walk and percolation, and discuss their respective behaviors depending on the geometric properties of the underlying group. The focus will be on the random processes and their properties, and we will use very few notions of geometric group theory. | |||||

401-4637-67L | On Hypothesis Testing | W | 4 credits | 2V | F. Balabdaoui | |

Abstract | This course is a review of the main results in decision theory. | |||||

Objective | The goal of this course is to present a review for the most fundamental results in statistical testing. This entails reviewing the Neyman-Pearson Lemma for simple hypotheses and the Karlin-Rubin Theorem for monotone likelihood ratio parametric families. The students will also encounter the important concept of p-values and their use in some multiple testing situations. Further methods for constructing tests will be also presented including likelihood ratio and chi-square tests. Some non-parametric tests will be reviewed such as the Kolmogorov goodness-of-fit test and the two sample Wilcoxon rank test. The most important theoretical results will reproved and also illustrated via different examples. Four sessions of exercises will be scheduled (the students will be handed in an exercise sheet a week before discussing solutions in class). | |||||

Abstract | This course offers a practically oriented introduction into regression modeling methods.

The last third of the course is dedicated to an introduction to generalized linear models: this includes the generalized additive model, logistic regression for binary response variables, binomial regression for grouped data and poisson regression for count data. | |||||

These algorithms are illustrated with the statistical software R. | |||||
