Modeling future lifetime as a fuzzy random variable

Shapiro, Arnold F. - In: Insurance: Mathematics and Economics 53 (2013) 3, pp. 864-870

A recent article by de Andrés-Sánchez and Puchades (2012) modeled life annuities as fuzzy random variables (FRVs). Their article was informative. However, it had the limitation that the FRV used to model the life annuity was not a granulated FRV. This followed because the authors assumed that...

A new approach of stochastic dominance for ranking transformations on the discrete random variable

Gao, Jianwei; Feng, Zhao - 2016

This paper develops some new stochastic dominance (SD) rules for ranking transformations on a random variable, which is … transformation functions and the probability distributions of the random variable. This is different from the existing SD approach … for transformations on the discrete random variable. Finally, a numerical example is provided to show the effectiveness of …

Forecasting using random subspace methods

Boot, Tom; Nibbering, Didier - 2016

Random subspace methods are a novel approach to obtain accurate forecasts in high-dimensional regression settings. We provide a theoretical justification of the use of random subspace methods and show their usefulness when forecasting monthly macroeconomic variables. We focus on two approaches....

Inference under covariate-Adaptive randomization

Bugni, Federico A.; Canay, Ivan A.; Shaikh, Azeem M. - 2016

This paper studies inference for the average treatment effect in randomized controlled trials with covariate-adaptive randomization. Here, by covariate-adaptive randomization, we mean randomization schemes that first stratify according to baseline covariates and then assign treatment status so...

Heads or Tails : The Impact of a Coin Toss on Major Life Decisions and Subsequent Happiness

Levitt, Steven D. - 2016

Little is known about whether people make good choices when facing important decisions. This paper reports on a large-scale randomized field experiment in which research subjects having difficulty making a decision flipped a coin to help determine their choice. For important decisions (e.g....

Karamata Method and the Maximum of Sums of Independent Random Variables

Lucic, Vladimir - 2016

We revisit the classical problem of convergence of the maximum of cumulative sums of IID random variables by introducing ideas from the Karamata's celebrated proof of the Hardy-Littlewood Tauberian Theorem [J. Karamata, Über die Hardy-Littlewoodschen Umkehrungen des Abelschen Stetigkeitssatzes,...
