Abstract: In some embodiments, a method receives input data to calculate an effect of a variable on a group for a plurality of methods. Methods in the plurality of methods calculate the effect of the variable for the input data using different logic. A plurality of sub-weights for methods in the plurality of methods are generated. The sub-weights are generated based on a balance metric, a dissimilarity metric, and a reliability metric. The method combines the plurality of sub-weights for methods in the plurality of methods to generate a final weight for the methods. The respective final weight is applied to an intermediate result from a respective method in the plurality of methods to generate a weighted intermediate result for the method. The method combines weighted intermediate results for the plurality of methods to generate a final result for the effect of the variable.

Abstract: A fluid container having an internal display substrate disposed within the internal volume of the container. The internal display substrate is preferably spaced from both the front and the back of the container, the spacing being maintained by the shape of the container, or by a combination of the shape of the container and the position of a feed tube associated with a pump for use with the container, or by retaining members disposed within the container. The internal display substrate is suitable for displaying a graphic. A fluid container having an integral air freshener is also disclosed, in which the air freshening effect may be provided by the fluid within the container.
