The correlation coefficient measures the correlation between two assets. It is a statistical measure between the two asset variables that ranges between -1.0 and 1.0. The lowest correlation two assets can have between each other is -1.0 meaning as one of the two correlated assets moves up, the other moves down in the same degree; this is a perfectly negative correlation Step 3: Calculate! Once you have your data in, you will now go to [STAT] and then the CALC menu up top. Finally, select 4:LinReg and press enter. That's it! You're are done!
