Mar 10, 2022 · local_offer Python NumPy Linear regression, in essence, is about computing the line of best fit given some data points. We can use NumPy's polyfit (~) method to find this line of best fit easily. Here's some toy dataset, which we will visualize using matplotlib: import matplotlib.pyplot as plt x = [1,2,4,5] y = [1,4,5,6] plt.scatter(x, y)

May 29, 2016 · Linear regression is a method used to find a relationship between a dependent variable and a set of independent variables. In its simplest form it consist of fitting a function y = w. x + b to observed data, where y is the dependent variable, x the independent, w the weight matrix and b the bias.
