Linear Regression

We can help understand data by building mathematical models, this is key to machine learning.
One of such models is linear regression, in which we fit a line to (x,y) data.

There are many modules for Machine Learning in Python, but scikit-learn is a popular one.

Install the required modules;


Then we start with a basic plot:

This will create a bunch of random data, which follows a linear path.
In a real life situation, you would use real world data instead of random numbers

We then use the model linear regression from the scikit-learn module.

then we define the linear space and predict the y values using the model.

finally we plot the data, summarizing with this code:

Then we find the fitting line.
