1. A method of selecting a desired number of informative data parameters from among a set of data parameters, the method comprising: obtaining, from a database with a processor, a set of data comprising a plurality of parameters representing a plurality of website metric variables; identifying a desired number of informative parameters to be selected from the plurality of parameters; creating, by the processor, a complete data set by filling in any missing values in the set of data using a method that does not substantially bias the statistics of the set of data; selecting, by the processor, a next most informative parameter from the complete data set by comparing variation in a non-selected parameter with variation of other non--selected parameters and by evaluating correlation of the non-selected parameter with a set of previously selected parameters; adding the selected next most informative parameter to the set of previously selected parameters; and repeating the selecting and adding operations until the desired number of informative parameters have been selected.
