Calculate statistical information between two sets of data. The data set can include all of the data in two DATACOL objects, or a subset of the data in the two DATACOL objects. The two DATACOL objects must be of the same length. The calculated statistics are returned as members of a VECTOR.
DataColX  DATACOL  The first column of data  
DataColY 
DATACOL 
The second column of data 

FirstPoint 
INDEX 
The first point to include in the data set (Optional) 

LastPoint  INDEX  The last point to include in the data set (Optional)
