TIME SERIES ANALYSIS

A very well known method to explore data is Time Series. It is used mainly to predictions but also to understand the hidden patterns of data. An obvious limitation is the necessity of a set of data big enough to extract patterns. Besides that limitation, Time Series still can work missing data, noised data or wrong data depending on the proportion of these type of data.
