Calculate statistical information between two sets of data.
The data set can include all of the data in two class 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.
REGULAR FUNCTION
Result = StatsTwo (DataColX, DataColY, FirstPoint, LastPoint)

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). |
