Beschreibung

Short description
This course covers some statistical methods that can help to take decisions in business using data. These basic concepts of the statistical testing and estimating theory should – to a large extent - be known from an introductory course on probability theory and statistics in any bachelor program.

Topics

  • Graphical and numerical characterizations of random variables and their distributions
  • Framework and basic applications of testing hypotheses and estimating parameters
  • Ordinary least squares method and its properties
  • Simple linear regression including parameter estimation, diagnostic plots, hypothesis testing, predictions and model specifications using log-transformations
  • Introduction to the software package R

Lernergebnisse

  • Students present the distributions of random variables graphically, calculate and interpret their moments.
  • Students can explain the framework of testing hypotheses and estimating parameters and apply basic procedures.
  • Students criticize the assumptions of basic testing and estimating procedures and generalize the conclusions correctly.
  • Students derive the minimal sample size for basic testing and estimating procedures.
  • Students apply the ordinary least squares method to derive estimators and compare the statistical properties of different estimators.
  • Students explain the classical linear model assumptions, run simple linear regressions, check the diagnostics plots, use log-transformations to specify models and interpret the results correctly.

Kompetenzen

Lehrmethoden

  • The e-learning platform Moodle will be used throughout the course for the dissemination of course material and discussions.
  • Students are usually asked to read corresponding parts of the lecture notes or of the textbook in order to prepare for the upcoming lectures in advance.
  • In the interactive lectures, statistical concepts will be introduced and motivated by discussing examples in detail. Assignments are offered to train these skills.
  • During office hours, individual problems may be discussed with the lecturer.
  • In order to analyse realistic data, the software package R will be used.

Voraussetzungen (inhaltlich)

We require basic knowledge of probability theory and statistics, which is usually presented in a basic course on these topics in any bachelor program. The module ''Statistik'' in the bachelor program at University of Liechtenstein serves as a guideline or benchmark for this previous knowledge.
This module is prerequisite for taking the Master’s thesis Module and writing the Master’s thesis
