Teaching

Course materials for statistics, financial analysis, and more.

I teach at ESSCA (statistics & information systems) and INSEEC (financial analysis, graduate level). Course materials live here and are updated each semester.

Annotating Course Pages

All course pages support collaborative annotation via Hypothesis. You can highlight any passage, leave a comment, or ask a question — directly on the page, without leaving the browser.

To get started:

  1. Create a free account at hypothes.is
  2. Open any course page (Statistics, Mathematical Analysis, Financial Analysis, AI guide)
  3. Click the ◀ tab on the right edge of the screen to open the annotation panel
  4. Select any text to highlight it or leave a note

Annotations are public by default — your questions and comments are visible to other students, which turns the course material into a shared living document. If you prefer to annotate privately, switch to Only me in the Hypothesis panel before posting.

Undergraduate

An introduction to probability and statistics as tools for modelling uncertainty and making sense of data. Covers continuous random variables, classical distributions, convergence theorems (LLN, CLT), and both descriptive and inferential statistics.

“Tous les modèles sont faux, mais certains sont utiles.” — George E. P. Box
