  This learning unit is not open to incoming exchange students!

Language
French
Prerequisites
The necessary mathematical concepts are
- first-order logic,
- set theory,
- To analyse :
    functions of one or more real variables: derivation and integration
    limits, sequences and series.
In terms of competence, it is necessary that students know how to perform a demonstration and can manipulate mathematical language in a formal way.
Prerequisites: LSINC1111, LSINC1112 and LSINC1113

The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.
Main themes
The aim here is to obtain for the student a deep and exact understanding of the fundamental concepts as well as training in probabilistic and statistical reasoning. The mathematical formalism is simplified but present. It is a question of using measurement theory in an intuitive way to extend the concept of counting towards an analytical definition of the laws of probability.
The basic subject of the calculation of probabilities is introduced by a few hours of descriptive statistics (processing of a table of numbers, calculation of mean, variance, etc.) which give rise to practical exercises with R. The necessary principles of probability for an introduction to inferential statistics are also defined. Particular emphasis will be placed on basic techniques, namely parameter estimation and hypothesis testing.
Learning outcomes

At the end of this learning unit, the student is able to :

.
  • to produce descriptive statistics and
  • to pose a hypothesis test and solve it, in order to interpret the reality masked by the dataset,
  • in function, to use the R language wisely to manipulate their data,
  • use the foundations of combinatorial analysis and probability calculation to determine the probabilities associated with different events,
  • to use the foundations of functional analysis, linear algebra and discrete mathematics to determine the probability laws of random phenomena,
  • to manipulate the usual theoretical laws to explain behaviors,
  • manipulate the laws associated with random variables studied simultaneously.
