This paper investigates the robustness of designed experiments for estimating linear functions of a subset of parameters in a general linear model against the loss of any t( U 1) observations. Necessary and sufficient conditions for robustness of a design under a homoscedastic model are derived....

Patents are rich sources of technical and commercial information. Bibliometric analysis of patents provides information on the nature and growth of the inventive activity; its international comparison; the active players from industry, academia and government; co-inventorship; linkages with...

Intellectual property rights have become a significant component of R&D policy in India. The inventor's productivity is a major concern of the publicly funded R&D organizations like the Council of Scientific and Industrial Research (CSIR). The paper examines the patenting activity of inventors...

The universal optimality of some block designs with unequal block sizes is studied, under the usual homoscedastic model and under a certain heteroscedastic model.
