Linear and Polynomial Regression in Python

Linear regression is the problem where a model(line) is built with available data and then learnt model is used to predict target value for future data. This is the most basic type of statistical method used for predictive analysis. In other words, it can be understood as finding a relationship between target value and the attributes of input data.The best model is where we get minimum error between predicted and actual values.
