STEYX

See Also

Returns the standard error of the predicted y-value for each x in the regression. The standard error is a measure of the amount of error in the prediction of y for an individual x.

Syntax

STEYX(known_y's,known_x's)

Known_y's is an array or range of dependent data points.

Known_x's is an array or range of independent data points.

Remarks

The arguments must be either numbers or names, arrays, or references that contain numbers.
If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
If known_y's and known_x's are empty or have a different number of data points, STEYX returns the #N/A error value.
The equation for the standard error of the predicted y is:
