Teaching Results

This course has as prerequisite the Statistics I course. It is a more advance level course of Statistics aiming to demonstrate its important applications to Economics and Finance Theory. After being introduced to the basic concepts of Probability theory, the students are being exposed to the Stochastic Processes theory which is considered as a the cornerstone in modelling various financial variables. Next, some introductory elements from the theory of estimation and Inferential Statistics are presented useful for the Econometric course which follows.

After the completion of the course, the student

  • must have understand the basic and crucial concepts of Probability and Statistics and their connection with other disciplines.
  • must have a good knowledge of the Statistical methods of estimation and their use in real problems
  • must be in position to select, describe and draw inferences from real data.
  • must know how to use testing hypotheses and identify the statistically significant results
  • will be in position to organize, apply, and monitoring a Statistical study.
  • must be able to interpret financial and economical phenomena with the use of statistical tools such as stochastic processes.
  • must know how to combine methods and tools for the development of statistical models in order to make decisions.

Skills

  • Retrieve, analyze and synthesize data and information with the use of necessary technologies.
  • Make decisions
  • Work autonomously
  • Work in team
