In this paper, we introduce a discrete analogue of weighted Hardy spaces on rooted trees and study composition operators between them in detail. particular, characterize bounded compact spaces.

background and objectives: mthe emergency severity index (esi) triage is commonly used in clinical settings to determine the patients’ emergency severity. however, the reliability of this index is not sufficiently explored. the present study examines the inter-rater reliability of esi by comparing triage ratings as performed by nurses and physicians. methods: this prospective cross-sectional st...

in this paper, the use of weighted pairwise likelihood instead of the full likelihood in estimating the parameters of the multivariate ar(1) is investigated. a closed formula for typical elements of the godambe information(sandwich information) is presented. some efficiency calculations are also given to discuss the feasibility andcomputational advantages of the weighted pairwise likelihood app...
