Correlation coefficient
The quick measure calculates the Pearson correlation coefficient between two measures within the category.
NAME:
Correlation coefficient
DESCRIPTION:
Calculate the Pearson correlation...
Linest is just a shortcut for LinestX with the <table> argument derived from the column references. The internal algorithm is the same.
Right, I was trying to determine why the Quick measure for Correlation Coefficient is giving an R value that when squared does not match Linest. Since the quick measure is forcing the summarization, it is only an estimated R value.
