WorksheetFunction.RSq Method
Returns the square of the Pearson product moment correlation coefficient through data points in known_y's and known_x's. For more information, see PEARSON. The r-squared value can be interpreted as the proportion of the variance in y attributable to the variance in x.
Syntax
expression.RSq(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 data points. |
| Arg2 | Required | Variant | Known_x's - an array or range of 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 are empty or have a different number of data points, RSQ returns the #N/A error value.
- If known_y's and known_x's contain only 1 data point, RSQ returns the #DIV/0! error value.
- The equation for the Pearson product moment correlation coefficient, r, is:
where x and y are the sample means AVERAGE(known_x's) and AVERAGE(known_y's).
RSQ returns r2, which is the square of this correlation coefficient.
