The results of Ross (1936), De Meillon (1936), Covell et al. (1938), Russell and Knipe (1939, 1940, 1941), and Russell et al. (1942) leave no doubt that wherever the mosquito vector of malaria spends its daytime hours inside houses, cowsheds, or outbuildings, routine spraykilling with pyrethrum sprays will effectively interrupt the transmission of malaria. This measure is based on the principle...

  This paper proposes a suitable benchmark for inefficient commercial bank branches by using Data Envelopment Analysis (DEA). In order to render an inefficient bank branch efficient, it is necessary to decrease inputs and increase outputs. As there are priorities for decreasing some certain inputs and increasing some certain outputs over other inputs and outputs, respectively, it is necessary ...

The Minimum Variance portfolio is subject to varying degrees of stability and robustness. We, therefore, propose a theoretical measure its relative Marchenko–Pastur derived random correlation matrix. We demonstrate practical use on the S&P 400, 500, 600 Russell 1000. Using historic market data from 2002 2021, we perform an optimisation empirical matrix eigenvalue distribution determine implied ...
