Analyzing and Visualizing Time Series Data
In the previous chapter, we learned where to obtain time series datasets, as well as how to manipulate time series data using pandas
, handle missing values, and so on. Now that we have the processed time series data, it’s time to understand the dataset, which data scientists call Exploratory Data Analysis (EDA). It is a process by which the data scientist analyzes the data by looking at aggregate statistics, feature distributions, visualizations, and so on to try and uncover patterns in the data that they can leverage in modeling. In this chapter, we will look at a couple of ways to analyze a time series dataset, a few specific techniques that are tailor-made for time series, and review some of the visualization techniques for time series data.
In this chapter, we will cover the following topics:
- Components of a time series
- Visualizing time series data
- Decomposing a time series
- Detecting and treating outliers...
