Estimation of E(Y) from a Population with Known Quantiles
‎In this paper‎, ‎we consider the problem of estimating E(Y) based on a simple random sample when at least one of the population quantiles is known‎. ‎We propose a stratified estimator of E(Y)‎, ‎and show that it is strongly consistent‎. ‎We then establish the asymptotic normality of the suggested estimator‎, ‎and prove that it ...
متن کاملHabitat Fragmentation and Species Extirpation in Freshwater Ecosystems; Causes of Range Decline of the Indus River Dolphin (Platanista gangetica minor)
Habitat fragmentation of freshwater ecosystems is increasing rapidly, however the understanding of extinction debt and species decline in riverine habitat fragments lags behind that in other ecosystems. The mighty rivers that drain the Himalaya - the Ganges, Brahmaputra, Indus, Mekong and Yangtze - are amongst the world's most biodiverse freshwater ecosystems. Many hundreds of dams have been co...
متن کاملThe estimation of fitnesses from population data.
HIS paper is concerned with certain statistical problems which arise in conTnection with attempts to estimate fitnesses from the genotype frequency data produced by artificial populations in which rapid changes in genotype frequencies are taking place. The special situation of concern here is the one in which the investigator wishes to obtain several estimates of fitness, each taken from small ...
متن کاملPopulation genetic structure of Guiana dolphin (Sotalia guianensis) from the southwestern Atlantic coast of Brazil
Sotalia guianensis is a small dolphin that is vulnerable to anthropogenic impacts. Along the Brazilian Atlantic coast, this species is threatened with extinction. A prioritized action plan for conservation strategies relies on increased knowledge of the population. The scarcity of studies about genetic diversity and assessments of population structure for this animal have precluded effective ac...
متن کاملRehabilitation of Old Naga-hammady Barrage Bridge
When the Old Naga Hammady Barrage has been constructed in 1930, it had a navigation lock on the western side of the barrage. In 1993, a new navigation lock has been constructed in the western side of the old lock. Each lock has a movable bridge to allow the high ships to pass from north to south and vice versa. The bridge of the new navigation lock is suffering from technical problems pampering...
