FORECAST

Calculates the expected y-value for a specified x based on a linear regression of a dataset.

Sample Usage

FORECAST(A1,A2:A100,B2:B100)

Syntax

FORECAST(x, data_y, data_x)

• x - The value on the x-axis to forecast.

• data_y - The range representing the array or matrix of dependent data.

• data_x - The range representing the array or matrix of independent data.

Notes

• Any text encountered in the value arguments will be ignored.
