linear regression equation example equation

For example, you can use linear regression to compute a trend line from manufacturing or sales data. You can use linear regression to determine a relationship between two continuous columns. However, linear regression is a useful and well-known method for modeling a response to a change in some underlying factor. There are other kinds of regression that use multiple variables, and also nonlinear methods of regression.

You can obtain the regression equation by adjusting a and b until the sum of the errors that are associated with all the points reaches its minimum. The coefficients a and b in the regression equation adjust the angle and location of the regression line. For example, the line in the following diagram is the best possible linear representation of the data.Įach data point in the diagram has an error associated with its distance from the regression line. The relationship takes the form of an equation for a line that best represents a series of data. The Microsoft Linear Regression algorithm is a variation of the Microsoft Decision Trees algorithm that helps you calculate a linear relationship between a dependent and independent variable, and then use that relationship for prediction.
