 [ComputeCoefficientOfDetermination](class_compute_coefficient_of_determination.xhtml)  ( [DataObjectContainer](class_data_object_container.xhtml)  *the\_field\_data*,    [DataObjectContainer](class_data_object_container.xhtml)  *the\_scalar\_data*   ) 

constructor which sets suitable defaults for all members

Parameters the\_field\_datathe subset of field data to be token as input. the\_scalar\_datathe subset of scalar data to be token as input. All quantity idents are extracted. Then for each of the n field quantities one creates a single regression model from what the C.o.D. can be comouted. The regression model contains the specified scalar quantities. (n\*1 new objects will be computed). As a default, the new C.o.D. field objects are appended to the field data quantities as individual designs. The design name is "cod\[scalar\_quantity\_ident\]". If multiple scalar quantities are selected, then the default ident is "cod\[multiple\]".
