StatsTwo()

Type: REGULAR FUNCTION

Purpose: Calculate statistical information between two sets of data.

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.

Usage: Result = StatsOne (DataColX, DataColY, FirstPoint, LastPoint)

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)
