1. A non-transitory computer-readable medium that stores computer-executable instructions that are executable by a computer processor, the instructions when executed embodying a method for determining the best fitting econometric models for explaining a set of variables that comprises the steps of: receiving (i) an input dataset comprising one or more sets of initial independent variables for insertion into a data grid, (ii) an input selection of criteria identifying types of econometric models to analyze, and (iii) a p-value cut-off threshold used to eliminate variables when performing an econometric model analysis; generating one or more sets of intermediate independent variables derived from said one or more sets of initial independent variables; generating a plurality of econometric models which are based on said selection criteria and said one or more sets of initial and intermediate independent variables, wherein each model of said plurality of models contains one or more independent variable from said one or more sets of initial and intermediate independent variables; calculating p-value for each dependent variable contained in each model of said plurality of models; storing each calculated p-value in memory; eliminating one or more of said one or more independent variables from each of said models as insignificant whenever said one or more independent variables have a p-value greater than said p-value cut-off threshold; and presenting a report of best-fitting models wherein all of the independent variables' p-value is greater than said p-value cut-off threshold.
