In this third article on Rplicate Series, We will share to you one way to replicate The Economist plot titled “I can’t get no …”. The plot making will also demonstrate ways to converting smooth line into linear line, using guides for legend, and adding a text annotation to a plot. The raw dataset used for this graph was obtained from a PDF, so we will also use tibble package to copy-paste the data into R.

One of many things to consider when we want to choose a machine learning model is the interpretability: can we analyze what variables or certain characteristics that contribute toward certain value of target variables? Some models can be easily interpreted, such as the linear or logistic regression model and decision trees, but interpreting more complex model such as random forest and neural network can be challenging. This sometimes drive the data scientist to choose more interpretable model…
