We are going to learn how to create a polynomial regression and make a prediction over a future value using python. The data set have been fetched from INE (national statistics institute) , that data is the EPA ( active population survey ), that tell us the national total (Spain), both genders. 16 and over are unemployed ( in thousands ). Example data: label serie rate 0 2002T1 0 2152.8 1 2002T2 1 2103.3 2 2002T3 2 2196.0 3 2002T4 3 2232.4 4 2003T1 4 2328.5 Data CSV can be downloaded here: https://drive.google.com/file/d/1fwvAZe7lah5DX8-DDEpmfeUDYQhKcfzG/view?usp=sharing Lets see how looks that data: Fine, as we can see the data describe a curve, so its for that because we want to use a polynomial regression. To try to approximate that curve we will use a grade 2 polynomial or
