### Parameters

Name

Required/Optional

Data Type

Description

Arg1

Required

Variant

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

Arg2

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

### Return Value

Double

• Arguments can either be numbers or names, arrays, or references that contain numbers.

• Logical values and text representations of numbers that you type directly into the list of arguments are counted.

• 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.

• Arguments that are error values or text that cannot be translated into numbers cause errors.

• If known_y's and known_x's have a different number of data points, STEYX returns the #N/A error value.

• If known_y's and known_x's are empty or have less than three data points, STEYX returns the #DIV/0! error value.

• The equation for the standard error of the predicted y is: where x and y are the sample means AVERAGE(known_x’s) and AVERAGE(known_y’s), and n is the sample size.
