What is Linest function formula?

The LINEST function calculates the statistics for a line by using the “least squares” method to calculate a straight line that best fits your data, and then returns an array that describes the line. Because this function returns an array of values, it must be entered as an array formula.

What is regression simple example?

Regression analysis makes use of mathematical models to describe relationships. For example, suppose that height was the only determinant of body weight. Weight = 80 + 2 x (70) = 220 lbs. In this simple linear regression, we are examining the impact of one independent variable on the outcome.

How is regression calculated?

The Linear Regression Equation The equation has the form Y= a + bX, where Y is the dependent variable (that’s the variable that goes on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the slope of the line and a is the y-intercept.
