Can't see a reason for that, but is likely a question for jeffrey_wang
@jeffrey_wang The measure forces the data to be summarized. Where Linest and Linestx are using the raw data to determine the best fit line and calculating all the variables. Would appear that for correlation coefficient, this is not a good quick measure, as the R value is skewed without being able to not use a summarization.
