Learning outcomes:

-     The use of regression analysis to predict the value of a dependent variable based on the value of an independent variable.

-     Evaluating the assumptions of regression analysis and what to do if they are violated.

-     Inferring the slope and correlation coefficient.

-     The development of multiple regression models.

-     The interpretation of its coefficients.

-     Determining which independent variables to include in a multiple regression model.

-     The use of categorical independent variables in a multiple regression model.

-     The description of the basic steps to be followed in each forecasting process.

-     The presentation of methodological tools for the preliminary investigation of numerical data and for checking the validity and reliability of prediction results.

-     Understanding of the most important forecasting methods.

-     The acquisition of knowledge about the general structure of Linear Programming problems and the necessary conditions for modeling a business problem in the form of Linear Programming.

-     Understanding the optimization mechanism in Linear Programming problems and identifying and interpreting the key elements of the process.

-     Understanding the process of sensitivity analysis and how to apply it to Linear Programming problems, as well as drawing key conclusions and evaluating them in decision making.

-     The perception of the main characteristics of a problem that is solved by applying the dynamic programming methodology.

-     Performing the calculations required to implement the dynamic programming algorithm.

-     Understanding the principle of sub-optimization to the extent that results obtained from the dynamic programming algorithm solution process can be interpreted.

-     The description of the main elements of the costs related to the management of the stocks and the determination of the factors that influence it.

-     The formulation of the analytical form of inventory management costs according to the operation mode of an inventory management system.

-     The explanation in business terms of the optimal inventory policy in terms of its effects on orders of raw materials, products, production schedules, etc.
