WorksheetFunction.RSq Method (Excel)

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.

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

  • 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: awfpears_ZA06051230where x and y are the sample means AVERAGE(known_x’s) and AVERAGE(known_y’s). RSQ returns r 2 , which is the square of this correlation coefficient.
