1. A system, comprising: a memory; a processor configured to execute components stored on the memory, the components comprising: a data set input component configured to receive a data set representing a first variable of interest, a second variable of interest, and independent variables, wherein values of the second variable of interest depend at least in part on values of the first variable of interest and the independent variables; a curve fitting component configured to perform, based on analysis of the data set, a first curve fitting from the first variable of interest to the second variable of interest for multiple sets of values of the independent variables to yield first curve fitting relationship data, and a second curve fitting from a first independent variable, of the independent variables, to the first curve fitting relationship data for multiple sets of values of a subset of the independent variables that does not include the first independent variable, the second curve fitting yielding second curve fitting relationship data; and a mapping component configured to generate mapping function data that defines a mapping from the first variable of interest to the second variable of interest as a function of the independent variables based at least in part on the first curve fitting relationship data and the second curve fitting relationship data.
