## Formula generator for FORECAST.LINEAR FUNCTION function

The FORECAST.LINEAR function is used to predict a future value based on existing data points. It uses linear regression to calculate the best-fit line through the data and then extrapolates the predicted value based on the independent variable x. The function requires two arrays: data_y, which contains the dependent variable values, and data_x, which contains the corresponding independent variable values.

## FORECAST.LINEAR FUNCTION formula syntax

The FORECAST.LINEAR function in Excel is used to predict a future value based on existing data points. The syntax for this function is: FORECAST.LINEAR(x, known_y's, known_x's) - x: The value for which you want to predict a future value. - known_y's: The array or range of dependent values (y-values) in the existing data. - known_x's: The array or range of independent values (x-values) in the existing data. Note that the known_y's and known_x's must have the same length or size. The function will calculate and return the predicted value for the specified x based on a linear regression model fitted to the known data.

## Use Cases & Examples

In these use cases, we use the FORECAST.LINEAR formula to predict future values based on existing data points. This formula takes into account the known x-values and y-values to calculate the linear regression equation.

## Sales Forecast

### Description

In this use case, we use the FORECAST.LINEAR function to predict future sales based on historical sales data. The function takes the independent variable x, which represents the future time period, and the arrays data_y and data_x, which contain the historical sales and corresponding time periods respectively.

### Result

FORECAST.LINEAR(x, data_y, data_x)

## Stock Price Prediction
