In management and administrative situations the need for planning is great and very valuable. Forecasting is a tool that aims to provide aid in decision making processes and efficient planning, whether that means learning from past mistakes, decreasing costs, better resource management amongst many other uses. When the data that's being analyzed is ordered over time then it's considered a time-series and its forecasting will try to estimate how that sequence of observations will behave in the future. Since time-series have specific traits it's interesting to convert time-series problems to regression ones. This thesis aims to automatically convert a time-series framework to a state-of-the-art regression framework and compare the two, trying to understand the advantages and disadvantages of the two approaches.
