Pedigree-Based Estimation of Reproductive Value [PDF]

open access: yesJournal of Heredity, 2019
AbstractHow successful an individual or cohort is, in terms of their genetic contribution to the future population, is encapsulated in the concept of reproductive value, and is crucial for understanding selection and evolution. Long-term studies of pedigreed populations offer the opportunity to estimate reproductive values directly. However, the degree

The sizes of BLRs and BH masses of double-peaked broad low-ionization emission line objects [PDF]

open access: yes, 2007
In this paper, the sizes of the BLRs and BH masses of DouBle-Peaked broad low-ionization emission line emitters (dbp emitters) are compared using different methods: virial BH masses vs BH masses from stellar velocity dispersions, the size of BLRs from ...

Case Study on Increasing Breeding Value Estimation Reliability of Reproductive Traits in Serbian Highly Prolific Large White and Landrace Sows

open access: yesAnimals, 2022
This study investigated the influence of the degree of connectedness on the reliability of the estimated breeding values (EBVs). The focal trait in the study was the number of piglets born alive (NBA) from sows of the highly prolific Large White and ...

The effect of inflation and form of investment on the estimated value of genetic improvement in farm livestock

open access: yesAnnales de Génétique et de Sélection Animale, 1978
High rates of interest (8 to 15%) commonly used in discounted cash flow analysis of genetic improvement schemes have tended to underestimate the value of the returns and to favour breeding programmes with short-term returns.

The study on estimated breeding value and accuracy for economic traits in Gyoungnam Hanwoo cow (Korean cattle)

open access: yesJournal of Animal Science and Technology, 2020
This study was conducted to construct basic data for the selection of elite cows by analyzing the estimated breeding value (EBV) and accuracy using the pedigree of Hanwoo cows in Gyeongnam. The phenotype trait used

Are Issuer Margins Fairly Stated? Evidence from the Issuer Estimated Value for Retail Structured Products

open access: yesForecasting, 2020
From 2014 to 2018, issuers of retail structured products in Germany established and calculated the Issuer Estimated Value (IEV), a fair value designed to offer more transparency for retail investors. By reporting the IEV in the product information sheet,

Bootstrapping Extreme Value Estimators

open access: yesJournal of the American Statistical Association, 2022
This article develops a bootstrap analogue of the well-known asymptotic expansion of the tail quantile process in extreme value theory. One application of this result is to construct confidence intervals for estimators of the extreme value index such as the Probability Weighted Moment (PWM) estimator.
