FORECASTCalculates 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.
