Demand and Sales Forecasting


Concepts for managing an archive of historical data, carrying out operations of selection, transformation, aggregation, etc.

Techniques presented

Preliminary analysis of the historical series, through graphical representations and study of the autocorrelations.


There are exercises for each of the topics covered.


Attendance at the INTRO course or having an intermediate knowledge of Statistics for Data Analysis is a prerequisite.
