Linear Regression is a machine learning algorithm based on supervised regression algorithm. Regression models a target prediction value based on independent variables. It is mostly used for finding out the relationship between variables and forecasting. The line for a simple linear regression model can be written as: y = b0 + b1 * x. 1. y = b0 + b1 * x. where b0 and b1 are the coefficients we must estimate from the training data. Once the coefficients are known, we can use this equation to estimate output values for y given new input examples of x. Figure 4. Graph of linear regression in problem 2. a) We use a table to calculate a and b. a) We first change the variable x into t such that t = x - 2005 and therefore t represents the number of years after 2005.
