Expansions for the Conditional Density and Distribution of a Standard Estimate

Stats
Conditioning is a very useful way of using correlated information to reduce the variability of an estimate. Conditioning an estimate on a correlated estimate, reduces its covariance, and so provides more precise inference than using an unconditioned ...

Estimation of the adjusted standard‐deviatile for extreme risks

Scandinavian Journal of Statistics, 2023
AbstractIn this paper, we modify the Bayes risk for the expectile, the so‐called variantile risk measure, to better capture extreme risks. The modified risk measure is called the adjusted standard‐deviatile. First, we derive the asymptotic expansions of the adjusted standard‐deviatile. Next, based on the first‐order asymptotic expansion, we propose two

5th-Order Multivariate Edgeworth Expansions for Parametric Estimates

Mathematics
The only cases where exact distributions of estimates are known is for samples from exponential families, and then only for special functions of the parameters. So statistical inference was traditionally based on the asymptotic normality of estimates. To

Standard and competing risk analysis of the effect of albuminuria on cardiovascular and cancer mortality in patients with type 2 diabetes mellitus

Diagnostic and Prognostic Research, 2018
Background Competing risks occur when populations may experience outcomes that either preclude or alter the probability of experiencing the main study outcome(s). Many standard survival analysis methods do not account for competing risks.

How sensitive are matching estimates of active labor market policy effects to typically unobserved confounders?

Journal for Labour Market Research, 2023
Using a rich and unique combined administrative-survey dataset, this paper explores how sensitive propensity score (PS) matching estimates of Active Labor Market Policies (ALMPs) based on the selection-on-observables assumption are to typically ...

Sampling uncertainty of UK design flood estimation

Hydrology Research, 2021
The UK standard for estimating flood frequencies is outlined by the flood estimation handbook (FEH) and associated updates. Estimates inevitably come with uncertainty due to sampling error as well as model and measurement error.

Estimating the feasibility of ‘standard speed-gun’ distances

Monthly Notices of the Royal Astronomical Society: Letters, 2023
ABSTRACT In a previous paper, we demonstrated a single-rung method for measuring cosmological distances in active galactic nuclei (AGNs) that can be used from low redshift (z < 0.1) to high redshift (z > 3). This method relies on the assumption that the variability seen in AGNs is constrained by the speed of light during a ...
