Overview of this book

Python and R allow you to extend Power BI capabilities to simplify ingestion and transformation activities, enhance dashboards, and highlight insights. With this book, you'll be able to make your artifacts far more interesting and rich in insights using analytical languages. You'll start by learning how to configure your Power BI environment to use your Python and R scripts. The book then explores data ingestion and data transformation extensions, and advances to focus on data augmentation and data visualization. You'll understand how to import data from external sources and transform them using complex algorithms. The book helps you implement personal data de-identification methods such as pseudonymization, anonymization, and masking in Power BI. You'll be able to call external APIs to enrich your data much more quickly using Python programming and R programming. Later, you'll learn advanced Python and R techniques to perform in-depth analysis and extract valuable information using statistics and machine learning. You'll also understand the main statistical features of datasets by plotting multiple visual graphs in the process of creating a machine learning model. By the end of this book, you’ll be able to enrich your Power BI data models and visualizations using complex algorithms in Python and R.

Correlation between numeric variables

The first thing we generally do to understand whether there is an association between two numeric variables is to represent them on the two Cartesian axes in order to obtain a scatterplot:

Figure 11.1 – A simple scatterplot

Using a scatterplot, it is possible to identify three important characteristics of a possible association:

  • Direction: It can be positive (increasing), negative (decreasing), or not defined (no association found or increasing and decreasing). If the increment of a variable corresponds to the increment of the other, the direction is positive; otherwise, it is negative:

  • Form: It describes the general form that association takes in its simplest sense. Obviously, there are many possible forms, but there are some that are more common, such as linear and curvilinear (nonlinear) forms:
