| ПРЕДСКАЗ | FORECAST |
The FORECAST function enables predictions based on linear regression using known data. This function is available in both Microsoft Excel and Google Sheets. Below, we»ll explore the syntax of the function, examples of its application, and how it can be utilized to solve problems.
Syntax
The syntax for the FORECAST function is as follows:
FORECAST(x, known_y"s, known_x"s)x— the X value for which you want to make a prediction.known_y"s— the known Y values.known_x"s— the known X values.
Usage Examples and Applications
Suppose you have a dataset with known X and Y values, and you need to predict the Y value for a new X. Consider the following dataset:
| X (known_x»s) | Y (known_y»s) |
|---|---|
| 1 | 10 |
| 2 | 20 |
| 3 | 30 |
Using the FORECAST function, we can predict the Y value for X=4:
=FORECAST(4, B2:B4, A2:A4)The result of this function will be the forecasted Y value for X=4, based on linear regression analysis of the provided data.
The FORECAST function is useful for predicting future values based on existing data, and for analyzing trends and patterns within data. Therefore, both in Excel and Google Sheets, the FORECAST function serves as a powerful tool for forecasting values through linear regression and can be applied in various fields where data analysis and making informed predictions are necessary.
