A linear regression is a statistical model that analyzes the relationship between a response variable (often called y) and one or more variables and their interactions (often called x or explanatory variables). You make this kind of relationship in your head all the time, for example, when you...

Linear regression is a supervised machine learning algorithm that is used to predict the continuous variable. The algorithm assumes that the relation between the dependent variable(Y) and independent variables(X), is linear and is represented by a line of best fit. In this chapter, we will lear...

Linear Regression: Linear regression stands as the most basic machine learning model, aiming to forecast an output variable with the help of one or more input variables. The depiction of linear regression involves an equation that takes a group of input values (x) and provides a projected output...
Linear regression is a powerful tool that can help us understand the relationship between variables and make predictions based on that relationship. For example, in finance, linear regression can be used to predict stock prices based on various economic indicators. In social sciences, it can be us...
Linear regression is a procedure for defining the relationship between linear related variables. In this process, we determine an equation that can be... Learn more about this topic: Statistical Analysis | Overview, Methods & Examples from
To summarize: in order to use gradient descent to learn the model coefficients, we simply update the weightswby taking a step into the opposite direction of the gradient for each pass over the training set – that’s basically it. But how do we get to the equation ...
