Tree-based conditional copula estimation

Dependence Modeling
This article proposes a regression tree procedure to estimate conditional copulas. The associated algorithm determines classes of observations based on covariate values and fits a simple parametric copula model on each class.

New phase transitions in Chern–Simons matter theory

Nuclear Physics B, 2016
Applying the machinery of random matrix theory and Toeplitz determinants we study the level k, U(N) Chern–Simons theory coupled with fundamental matter on S2×S1 at finite temperature T. This theory admits a discrete matrix integral representation, i.e. a

An Alternative Asymptotic Analysis of Residual-Based Statistics [PDF]

This paper presents an alternative method to derive the limiting distribution of residual-based statistics. Our method does not impose an explicit assumption of (asymptotic) smoothness of the statistic of interest with respect to the model's parameters ...

Asymptotic structure of Einstein-Maxwell-dilaton theory and its five dimensional origin

Journal of High Energy Physics, 2019
We consider Einstein-Maxwell-dilaton theory in four dimensions including the Kaluza-Klein theory and obtain the general asymptotic solutions in Bondi gauge.

Asymptotic properties of a goodness-of-fit test based on maximum correlations [PDF]

We study the efficiency properties of the goodness-of-fit test based on the Qn statistic introduced in Fortiana and Grané (2003) using the concepts of Bahadur asymptotic relative efficiency and Bahadur asymptotic optimality.

An Asymptotic Analysis of Nearly Unstable inar (1) Models [PDF]

This paper considers integer-valued autoregressive processes where the autoregression parameter is close to unity.We consider the asymptotics of this `near unit root' situation.The local asymptotic structure of the likelihood ratios of the model is ...

Discovering asymptotic expansions for problems in mechanics using symbolic regression [PDF]

Recently, symbolic regression (SR) has demonstrated its efficiency for discovering basic governing relations in physical systems. A major impact can be potentially achieved by coupling symbolic regression with asymptotic methodology.

Asymptotic safety within on-shell perturbation theory

Journal of High Energy Physics
We investigate the renormalisation of Einstein gravity using a novel subtraction scheme in dimensional regularisation. The one-loop beta function for Newton’s constant receives contributions from poles in even dimensions and can be mapped to the beta ...

Asymptotic Maturity Behavior of the Term Structure [PDF]

Pricing and hedging of long-term interest rate sensitive products require to extrapolate the term structure beyond observable maturities. For the resulting limiting term structure we show two results by postulating no arbitrage in a bond market with ...
