Journal of Forecasting, EarlyView.ABSTRACT Using online job advertisement data improves the timeliness and granularity depth of analysis in the labor market in domains not covered by official data. Specifically, its variation over time may be used as an anticipator of official employment variations.

Entropy, 2017 Copula functions have been extensively used to describe the joint behaviors of extreme hydrological events and to analyze hydrological risk. Advanced marginal distribution inference, for example, the maximum entropy theory, is particularly beneficial for

Alternative Approaches for Estimating Highest‐Density Regions
International Statistical Review, EarlyView.Summary Among the variety of statistical intervals, highest‐density regions (HDRs) stand out for their ability to effectively summarise a distribution or sample, unveiling its distinctive and salient features. An HDR represents the minimum size set that satisfies a certain probability coverage, and current methods for their computation require ...

Hybrid Clayton-Frank Convolution-Based Bivariate Archimedean Copula
Journal of Probability and Statistics, 2018 This study exploits the closure property of the converse convolution operator to come up with a hybrid Clayton-Frank Archimedean copula for two random variables.

Non‐parametric Copula Estimation Under Bivariate Censoring [PDF]
Scandinavian Journal of Statistics, 2015 AbstractIn this paper, we consider non‐parametric copula inference under bivariate censoring. Based on an estimator of the joint cumulative distribution function, we define a discrete and two smooth estimators of the copula. The construction that we propose is valid for a large range of estimators of the distribution function and therefore for a large ...

Journal of Management Studies, EarlyView.Abstract Integrating the attention‐based view with the strategic leadership interfaces perspective, we propose a theoretical model of situational urgency mechanisms influencing the allocation of CEOs' attention towards responsive actions. Specifically, we theorize upon the role of humility, which leads CEOs towards embracing interfaces and makes them ...

Acquirer Strategic Orientations, Integration Decisions, and Performance
Journal of Management Studies, EarlyView.Abstract Integration decisions are not isolated, as they are embedded in an organizational context. Using a multi‐country sample (Nordics, German speaking Europe, and China) of small‐ and medium‐sized acquirers, we explore the influence of firm strategic orientations on how managers conceptualize acquisitions, make integration decisions, and impact ...

Calibrating and Simulating Copula Functions in Financial Applications
Frontiers in Applied Mathematics and Statistics, 2021 Copula functions can be utilized in financial applications to determine the dependence structure of the financial asset returns in the portfolio. Empirical evidence has proved the inadequacy of the multi-normal distribution, traditionally adopted to ...

Multiple Changepoint Detection for Non‐Gaussian Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT This article combines methods from existing techniques to identify multiple changepoints in non‐Gaussian autocorrelated time series. A transformation is used to convert a Gaussian series into a non‐Gaussian series, enabling penalized likelihood methods to handle non‐Gaussian scenarios.

LABOUR, EarlyView.ABSTRACT The present paper provides an overall framework to afford the problem of non‐representativeness and non‐random selectivity arising from online job ads data, using Generalized sample selection models and Eurostat benchmark data. We jointly model the outcome intensity (number of online job ads in observed profiles, whose levels are defined by ...
