WorksheetFunction.StEyx Method
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
expression.StEyx(Arg1, Arg2)
expression A variable that represents a WorksheetFunction object.
Parameters
| Name | Required/Optional | Data Type | Description |
|---|---|---|---|
| Arg1 | Required | Variant | Known_y's - an array or range of dependent data points. |
| Arg2 | Required | Variant | Known_x's - an array or range of independent data points. |
Return Value
Double
Remarks
- 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.
