# Statistics and probability

Course
2019-2020

## Description

The first half of this course is an introduction to probability theory. We start with the definition of a probability distribution, and discuss conditional probabilities and (conditional) independence. Next, we introduce a number of well known and much used probability distributions and consider joint distributions of multiple, dependent variables. We define the expectation, variance and covariance and finally we discuss two important Theorems: the Law of Large Numbers and the Central Limit Theorem.

The second half of the course is an introduction to statistics. On the basis of data we try to draw conclusions about the (random) process that generated those data. We discuss estimation theory where we attempt to find the probability distribution that “best” fits the data. In particular, we consider the method of maximum likelihood. Next, we look at testing hypotheses, where we try to determine if the data are consistent with some hypothesis, or not.

## Course objectives

Obtain introductory knowledge on Probability Theory and Statistics.

## Time Table

See the Leiden University students' website for the Statistical Science programme -> Schedules

## Mode of Instruction

This course is a combination of lectures, problem sessions and computer practicals.

## Assessment method

Two written exams, one for the Probability part and one for the Statistics part, each accounts for 50% of the grade.

Date information about the exam and resit can be found in the Time Table pdf document under the tab “Masters Programme” at T.B.A.. The room and building for the exam will be announced on the electronic billboard, to be found at the opposite of the entrance, the content can also be viewed here http://info.liacs.nl/math/.
