Java for Data Science

Summary

In this chapter, we provided a brief introduction to the basic statistical analysis techniques you may encounter in data science applications. We started with simple techniques to calculate the mean, median, and mode of a set of numerical data. Both standard Java and third-party Java APIs were used to show how these attributes are calculated. While these techniques are relatively simple, there are some issues that need to be considered when calculating them.

Next, we examined linear regression. This technique is more predictive in nature and attempts to calculate other values in the future or past based on a sample dataset. We examine both simple linear regression and multiple regression and used Apache Commons classes to perform the regression ...
