Formula Generator - FORECAST.LINEAR 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.How to generate an FORECAST.LINEAR formula using AI.
To obtain the FORECAST.LINEAR formula for your data, you can ask the AI chatbot the following question: "What is the formula in Excel to calculate a linear forecast for a given set of data points?"
FORECAST.LINEAR 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.
Sales Forecast
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.
FORECAST.LINEAR(x, data_y, data_x)
Stock Price Prediction
In this use case, we use the FORECAST.LINEAR function to predict future stock prices based on historical price 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 prices and corresponding time periods respectively.
FORECAST.LINEAR(x, data_y, data_x)
Demand Forecasting
In this use case, we use the FORECAST.LINEAR function to forecast future demand for a product 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.
