1. A method for generating a model of a process in a process plant, comprising:

  • collecting a plurality of groups of data sets for the process in the process plant, the data sets generated from process variables of the process;

    generating a plurality of regression models of the process using the groups of data sets, wherein each regression model is generated using a corresponding group of data sets from the plurality of groups, and wherein each regression model comprises a plurality of corresponding parameters generated using the corresponding group of data sets;

    generating a composite model of the process to include the plurality of regression models;

    generating a new model of the process using parameters of at least two of the regression models; and

    revising the composite model of the process to replace the at least two of the regression models with the new model.
