Learning Optimization: from beginner to advanced level (article 10)

How to fit a straight line with discrete inconsistent data points? Consider the following dataset:

Is there a straight-line which passes through these data? The answer is “No”. Hence, we find the “best fit” of the dataset. Application of “best fit”:

1.??????Data analysis from scatterplot

2.??????Determine trend in a dataset

3.??????Prediction and Forecast

Here comes Recursive Least Square Algorithm (RLS):

In Python:?

Comment if you want elaboration on the applications mentioned above!?
