The trainer, Mozard LOUIS, was very clear in his explanations and patient with the group. The course content was comprehensive, covering both theory and practical examples.

I think my level when I started the course was a bit too low to grasp the various concepts – and, above all, the exercises – effectively enough. I found it difficult to follow the line of reasoning during the exercises.

It’s a packed but very effective and essential course. Thanks to Mozard for these two days. It’s a good refresher for going over the basics of descriptive statistics and modelling. Well done
