Efficient Support of Statistical Operations [PDF]
IEEE Transactions on Software Engineering, 1985 Most research in statistical databases has concentrated on retrieval, sampling, and aggregation type statistical queries. Data management issues associated with computational statistical operations have been ignored. As a first step towards integrating database management support of statistical operations, we have analyzed the performance of X'X, the ...

Measuring Operating Efficiency
Journal of the Operational Research Society, 1975 An efficiency of a given variable is often defined as the actual value expressed as a percentage of the maximum value. It seems attractive to generalize the efficiency concept to the overall operation of a (sub-) system, e.g. a plant or a division of a firm. Two such operating efficiency measures are developed.
