Linear regression is the simplest approach to the regression task based on a parametric model representation. This chapter covers both plain linear regression and augmented versions thereof, breaking the linearity limitation. The discussion of model representation and creation techniques maintains a higher ...

Practical linear regression algorithms use an optimization technique known as gradient descent (Fletcher, 1963; Marquardt, 1963) to identify the combination of b0 and b1 which will minimize the error function given in Eq. (5.4). The advantage of using such methods is that even with several predi...

It starts with the basic ideas, presents the definitions, treats some examples, considers the relationship between a ...
epsilon represents the error term, which accounts for the variability in Y that is not explained by X. The goal of linear regression is to find the best values for Beta_0 and Beta_1 that minimize the sum of squared errors (the vertical distance between the actual data points and the pred...

Simple linear regression is used to model the relationship between two continuous variables. Often, the objective is to predict the value of an output variable based on the value of an input variable.
