Properties of Hierarchical Archimedean Copulas [PDF]

In this paper we analyse the properties of hierarchical Archimedean copulas. This class is a generalisation of the Archimedean copulas and allows for general non-exchangeable dependency structures. We show that the structure of the copula can be uniquely

Product Introduction Events and Stock Returns: A Meta‐Analysis

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary Product introduction events are frequent across industries, countries, and other contexts and part of the innovation strategy of many companies. However, the future performance of new products is uncertain, posing significant risks for firms and investors and leading to heterogeneous stock market responses.

On Testing for Independence Between Generalized Error Models of Several Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT We define generalized innovations associated with generalized error models having arbitrary distributions, that is, distributions that can be mixtures of continuous and discrete distributions. These models include stochastic volatility models and regime‐switching models with possibly zero‐inflated regimes.

Kendall's Tau as the test for trend in time series data

, 2012
When using nonparametric tests test time series data for trends, most require that the data the model independent and identically distributed. course, real-world data not always meet this requirement.

Moving Aggregate Modified Autoregressive Copula‐Based Time Series Models (MAGMAR‐Copulas)

Journal of Time Series Analysis, EarlyView.
ABSTRACT Copula‐based time series models can model univariate and stationary time series in a flexible way by decomposing the joint distribution of consecutive observations into a copula and the stationary distribution. Implicitly, this approach assumes a finite Markov order. In reality, a time series may not follow the Markov property.
