# Quantitative Methods in Finance

## Descrizione

This course will introduce the methods for inferential statistics with applications focusing on finance.
The free-ware statistical software "R" (free version of the commercial software "Splus", one of the main software used for statistical purposes) will be used to perform hypothesis tests and construct confidence intervals building on the knowledge of the software acquired in the Introduction to Statistics course which is a prerequisite of the course.

Data, imported from an Excel spreadsheet into "R", will be analysed from an inferential point of view.

Prerequisites
The students will be assumed to have learned, in the course Introduction to Statistics (which is a pre-requisite), the following concepts of probability theory and descriptive statistics. They need further more to know the basics on the free-ware statistical software “R” (also acquired in the Introduction to Statistics course).

Probability Theory:
Introduction to probability:
definitions, concept of marginal and joint probability, low of total probability, conditional probability, notion of independence
Random variables:
discrete (Bernoulli, Binomial, Geometric, Poisson, Uniform) continuous (Uniform, Gaussian or Normal, Exponential, Student-T, Chi-square)

Descriptive Statistics:
Univariate:
measure of location (mean, median, mode) and dispersion (variance, std deviation, quantiles)
Bivariate:
two way tables, joint and marginal distributions, covariance and correlation
Graphical instruments to visualize data

Details of the course
The course focuses on inferential statistics both theoretical and applied (with a focus on financial applications).

Main topics:
- Theory of point estimation (methods and properties of estimators)
- Construction of confidence intervals
- Theory of hypothesis tests

Lecture notes will be available on the e-learning website
