RSQ function: Description, Usage, Syntax, Examples and Explanation

Explanation of RSQ function

• 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.
