Calculate statistical information on a set of data.
The data set can include all of the data in a class DATACOL object, or a subset of the data in a DATACOL object. The calculated statistics are returned as members of a VECTOR.
REGULAR FUNCTION
Result = StatsOne (DataCol, FirstPoint, LastPoint)
DataCol |
DATACOL |
The column of data upon which to calculate the statistics. |
FirstPoint |
INDEX |
The first point to include in the data set (Optional). |
LastPoint |
INDEX |
The last point to include in the data set (Optional). |
