Flexible negative binomial mixtures for credible mode inference in heterogeneous count data from finance, economics and bioinformatics

Cross, Jamie; Hoogerheide, Lennart; Labonne, Paul; van … - 2024

exist involving multimodal and asymmetric count data distributions due to heterogeneity of the underlying population. For … and DNA count data, we find coherent evidence on number and location of modes, fat tails and implied uncertainty measures … accurate measures of uncertainty and risk which improves prediction and policy analysis using multimodal and asymmetric count …

Land-redistribution and coercive violence

Gudibande, Rohan Ravindra; Nandy, Abhinaba; Srivastava, … - 2024

In a post land reformenvironment, violence and redistribution are substitutes for an opportunistic incumbent attempting industrialization. We setup a theoretical model to explore this relationship for individual and group level violence across two types of policy driven post...

Joint effects of ill-health, health shocks and social protection on the intensive margin of labour supply : evidence from Malawi

Ken Chamuva Shawa; Hollingsworth, Bruce; Zucchelli, Eugenio - 2024

Background There is sparse evidence on the joint effects of ill-health, health shocks and social protection on the intensive margin of labour supply, particularly in developing countries. We interact ill-health and health shocks with access to social protection and estimate their joint effects...

On the validity of granger causality for ecological count time series

Papaspyropoulos, Konstantinos G.; Kugiumtzis, Dimitris - In: Econometrics : open access journal 12 (2024) 2, pp. 1-21

Knowledge of causal relationships is fundamental for understanding the dynamic mechanisms of ecological systems. To detect such relationships from multivariate time series, Granger causality, an idea first developed in econometrics, has been formulated in terms of vector autoregressive (VAR)...

On the Poisson-transmuted exponential distribution and its application to frequency of claim in actuarial science

Shamsul Rijal Muhammad Sabri; Adetunji, Ademola Abiodun - In: Statistics in transition : an international journal of … 25 (2024) 2, pp. 103-120

This study proposes a new discrete distribution in the mixed Poisson paradigm to obtain a distribution that provides a better fit to skewed and dispersed count observation with excess zero. The cubic transmutation map is used to extend the exponential distribution, and the obtained continuous...
