Namespace: Geosoft.Desktop.GXNet
Assembly: geosoft.desktop.gxnet (in geosoft.desktop.gxnet.dll)
Notes
Created for duplicate sample handling in CHIMERA. On input, a numeric or text VV containing data values, and a sample type VV. Sample pairs have types "1" and "2". This routine searches for types in order "1 2 1 2", and calulates the unnormalized relative variance, defined as the sum of the squared differences between duplicates divided by the sum of the squared mean values of the duplicates. (To get the true rel.var., divide by N-1, where N is the number of duplicate pairs used.) Samples out of order, unmatched pairs, or when the sample type does not equal "1" or "2" are ignored.
Syntax
