Novel time series methods in economic forecasting: SutteARIMA evidence from Indonesian Consumer Price Index and currency exchange rates

open access: yesCogent Economics & Finance
Economic forecasting demands precision. Yet traditional models often stumble when confronted with real-world complexity – the messy interplay of linear trends, non-linear disruptions and seasonal fluctuations that characterize financial time series. This

Fast rate of convergence in high dimensional linear discriminant analysis

open access: yes, 2010
This paper gives a theoretical analysis of high dimensional linear discrimination of Gaussian data. We study the excess risk of linear discriminant rules.

Measurability of functionals and of ideal point forecasts

open access: yes, 2022
The ideal probabilistic forecast for a random variable $Y$ based on an information set $\mathcal{F}$ is the conditional distribution of $Y$ given $\mathcal{F}$.

Current philosophical perspectives on drug approval in the real world

open access: yesJournal of Causal Inference
The evidence-based medicine approach to causal medical inference is the dominant account among medical methodologists. Competing approaches originating in the philosophy of medicine seek to challenge this account.

Adaptive Higher-order Spectral Estimators

open access: yes, 2017
Many applications involve estimation of a signal matrix from a noisy data matrix. In such cases, it has been observed that estimators that shrink or truncate the singular values of the data matrix perform well when the signal matrix has approximately low

Estimating the mean function of a Gaussian process and the Stein effect [PDF]

open access: yes, 1983
The problem of global estimation of the mean function [theta](·) of a quite arbitrary Gaussian process is considered. The loss function in estimating [theta] by a function a(·) is assumed to be of the form L([theta], a) = [integral operator] [[theta](t)

Spectral cut-off regularizations for ill-posed linear models

open access: yes, 2014
International audienceThis paper deals with recovering an unknown vector β from the noisy data Y = Xβ + σξ, where X is a known n × p-matrix with n ≥ p and ξ is a standard white Gaussian noise.

Testing the order of a model

open access: yes, 2006
This paper deals with order identification for nested models in the i.i.d. framework. We study the asymptotic efficiency of two generalized likelihood ratio tests of the order.
