PEARSON

PEARSON(array1, array2)

Returns the pearson product moment correlation coefficient.

array1	The first array of independent values.
array2	The second array of dependent values.

REMARKS

* The pearson product moment correlation coefficient is a dimensionless index that ranges from -1.0 to 1.0 inclusive and reflects the extent of a linear relationship between two data sets.
* The arguments must be either numbers or names, array constants, or references that contain numbers.
* 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.
* If "array1" and "array2" are empty, then #N/A is returned.
* If "array1" and "array2" have a different number of data points, then #N/A is returned.
