On expectation propagation for generalised, linear and mixed models [PDF]

open access: yes, 2018
© 2018 Australian Statistical Publishing Association Inc. Published by John Wiley & Sons Australia Pty Ltd. Expectation propagation is a general approach to deterministic approximate Bayesian inference for graphical models, although its literature is ...

Variance analysis and linear contracts in agencies with distorted performance measures [PDF]

open access: yes, 2007
This paper investigates the role of variance analysis procedures in aligning objectives under the condition of distorted performance measurement. A riskneutral agency with linear contracts is analyzed, whereby the agent receives postcontract, pre ...

A Law of the Iterated Logarithm for Sub-Linear Expectation Under a General Moment Condition

open access: yesMathematics
In this paper, we obtain the law of the iterated logarithm under a general moment condition with respect to sub-linear expectation. We present a novel proof by combining the exponential inequality with the subsequence method.

Lindeberg’s central limit theorems for martingale like sequences under sub-linear expectations [PDF]

open access: yesScience China Mathematics, 2020
The central limit theorem of martingales is the fundamental tool for studying the convergence of stochastic processes, especially stochastic integrals and differential equations. In this paper, general central limit theorems and functional central limit theorems are obtained for martingale like random variables under the sub-linear expectation.

A complete convergence theorem of the maximum of partial sums under the sub-linear expectations

open access: yesFilomat, 2022
Let {X,Xn; n ? 0} be a sequence of independent and identically distributed random variables in a sub-linear expectation space (?,H,?). We establish a complete convergence theorem of the maximum of partial sums max1?j?n |?j i=1 Xi| under optimal moment condition in a sub-linear expectation space.

On Characterizations of Conditional Expectation [PDF]

open access: yes, 1973
In the following (Ω, α, μ) is a totally σ-finite measure space except where noted. For a sub-σ-algebra β ⊂ α, the conditional expectation E{f|β} off given β is a function measurable relative to β, such thatIn [5] R.G.Douglas proved, among other things ...

Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization

open access: yesREM: International Engineering Journal, 2021
Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore ...

Strassen’s Law of the Iterated Logarithm under Sub-linear Expectations

open access: yesActa Mathematica Sinica, English Series
We establish the Strassen's law of the iterated logarithm for independent and identically distributed random variables with $\hat{\mathbb{E}}[X_1]=\hat{\mathcal{E}}[X_1]=0$ and $C_{\mathbb{V}}[X_1^2]<\infty$ under sub-linear expectation space with a countably sub-additive capacity $\mathbb{V}$.
