Linear regression is a statistical technique which can be used for analyzing the relationship between one or more independent variables and a response variable. It's commonly used in economics, business, and social science research.

Linear Regression is a statistical method for estimating the relationships among variables. It does this by fitting a line (typically, but not always) through the data points.

It is a statistical technique that uses a line to make predictions about future data. This is useful because it allows you to model the relationship between two variables, but it also means that you can use linear regression to predict values of new variables.
