In the last lecture, you learnt when linear regression modelling can be applied.
You will often see the terms ‘prediction’ and ‘projection’ being used interchangeably; however, in terms of modelling, these are different applications. Let’s learn the difference between them.
In the previous segment, you got a basic idea of interpolation and extrapolation. Let’s now learn more about these in detail.
In this lecture, you learnt that linear regression can be effectively used for interpolation, but extrapolation may not necessarily be effective/accurate.
In the next lecture, you will look at a case study for a media company.
