FORECAST(x1, ky1’s, kx1’s)
Where X1 is the data point, ky1 is the dependent array or range of data and ky2
is the independent array or range of data.
It Predicts or calculates a future value by using existing values. The predicted value is a y1-value for a given x1-value.
· FORECAST displays an error, when x is nonnumeric.
· when the variance of kx1’s equals zero FORECAST displays errror.
· The equation for FORECAST is a+bx, where:
and:
and where x and y are the sample means AVERAGE(kx1's) and AVERAGE(ky1's).
