One of such functions is LINEST, which is designed to perform linear regression analysis and return related statistics.

In this tutorial for beginners, we will touch only lightly on theory and underlying calculations.

Our main focus will be on providing you with a formula that simply works and can be easily customized for your data.

The function uses the least squares method to find the best fit for your data.

Optionally, it can also return additional statistics for the regression analysis as shown in this example.

If it is entered as a regular formula, only the first slope coefficient is returned.

It is the default behavior of the LINEST function, but if youd like to hide the error notations, wrap your LINEST formula into IFERROR as shown in this example.

Below, you will find a few examples of using LINEST formulas in Excel that will hopefully help to sink the theoretical knowledge in:).

If plotted on a graph, it is the value at which the regression line crosses the y-axis.

For this, you use LINEST in combination with the SUM or SUMPRODUCT function.

In this case, you need to input the 1 constant in some cell too because you cannot mix references and values in an array constant.

For example, with the advertising budget of 50 (x 2 ) and an average monthly rainfall of 100 mm (x 1 ), the formula goes as follows.

As pointed out earlier, when the Excel LINEST function is used to do multiple regression, it returns the slope coefficients from right to left.

In our example, the Advertising coefficient is returned first, and then the Rainfall coefficient.

To calculate the predicted sales number correctly, you need to multiply the coefficients by the corresponding x values, so you put the elements of the array constant in this order: 50,100,1.

The last element is 1, because the last value returned by LINEST is the intercept that should not be changed, so you simply multiply it by 1.

Applied to our sample data, the formula takes the following shape.

The value of R 2 is the result of dividing the regression sum of squares by the total sum of squares.

The smaller the numbers, the more certain you can be about your regression model.

The LINEST function in Excel returns the residual degrees of freedom, which is the total df minus the regression df.

You can use the degrees of freedom to get F-critical values in a statistical table, and then compare the F-critical values to the F statistic to determine a confidence level for your model.

It is the sum of the squared differences between the predicted y-values and the mean of y, calculated with this formula: ( - ) 2.
