1. A method of processing interpolated data, comprising: accessing a set of combined input data comprising a set of predetermined input data and a set of interpolated input data, the set of interpolated input data being generated to conformally map the set of combined input data to a set of target output data and comprising a set of variables; performing a variational analysis on at least a first variable in the set of variables in the set of interpolated input data; determining a change in at least one of the remaining variables in the set of variables in the set of interpolated input data caused by the variational analysis performed on the at least first variable in the set of interpolated input variables; and applying a set of validation rules to the change in the at least one remaining variable to validate or reject the value of the at least first variable in the set of interpolated inputs.
