Accurately estimating the cardinality of aggregate views is crucial for logical and physical design of data warehouses. While the warehouse is under development and data are not available yet, the approaches based on accessing data cannot be adopted. This paper proposes an approach to estimate the cardinality of views based on a-priori information derived from the application domain. We face th...

We focus on the problem of constructing functions that are able to measure the degree of consensus for a set of inputs provided over the unit interval. When making evaluations based on inputs from multiple criteria, sources or experts, the resulting output can be seen as the value which best represents the individual contributions. However it may also be desirable to know the extent to which th...

In many cases, aggregate data is used to make inferences about individual level behavior. If there are social interactions in which one person’s actions influence his neighbor’s incentives or information, then these inferences are inappropriate. The presence of positive social interactions, or strategic complementarities, implies the existence of a social multiplier where aggregate relationship...

Existing statistical ultimate (Frisbee) analyses rely on data aggregates to produce numeric statistics, such as completion percentage and scoring rate, that assess strengths and weaknesses of individuals and teams. We leverage sequential, location-based data to develop completion and scoring maps. These are visual tools that describe the aggregate statistics as a function of location. From thes...

Dialectometric techniques for analyzing variation in the aggregate are maturing rapidly, but there is still little agreement on how to extract linguistic structure from aggregate comparison. The present paper explores one means of comparing aggregate analyses in order to determine linguistically concise restrictions, essentially the use of factor analysis. Using the Southern states data which G...
