1. A system comprising: a data store containing data, for performance information data for each of a plurality of locations, wherein the performance information data is arranged in discrete time periods; and an analytics server coupled to the data store and programmed to: compile a data set from the data store of performance information data for a plurality of locations within a selected time period, wherein the performance information data is arranged in discrete time periods within the selected time period; generate a first index value for the performance information data of the data set for each location based on a comparison of the performance information data to an average for each location; generate a second index value for the performance information data based upon a comparison of the first index value to an average for the time period; execute an outlier algorithm to determine any discrete time period having performance information data that represents an outlier; generate a blacklist file representing each discrete time period in the data set having performance information data that represents an outlier; select a new data set based upon a query of the data store for performance information data during the discrete time periods during the selected time period that are not listed on the blacklist file as representing an outlier; modify an algorithm for analyzing an initiative based upon the selection of the new data set to exclude any discrete time period where the performance information data represents an outlier, the modified algorithm iteratively computing the performance information data to identify outlier performance information data and to remove the outlier performance information data, wherein the modified algorithm is iteratively executed until it reaches a predetermined level of outlier threshold; execute the modified algorithm to analyze the initiative at the plurality of locations; and generate for display on a client computing device a user interface having data representing the analysis of the initiative at the plurality of locations, the user interface excluding the outlier performance information data removed.
