Modeling Count Distributions via Skewness–Kurtosis Orthogonal Expansions
MathematicsWe develop a semi-parametric framework for representing discrete probability mass functions through orthogonal polynomial representations. Classical count models, such as the Poisson and negative binomial distributions, impose restrictive structural ...

Local sequence and sequencing depth dependent accuracy of RNA-seq reads
BMC Bioinformatics, 2017 Background Many biases and spurious effects are inherent in RNA-seq technology, resulting in a non-uniform distribution of sequencing read counts for each base position in a gene.

Business‐Like Narrative and Public Engagement: Evidence From TED Talks on Nonprofit Issues
Nonprofit Management and Leadership, EarlyView.ABSTRACT While the trend of nonprofits adopting business‐like practices has been widely discussed, limited attention has been paid to how the broader public responds to this shift. One way to capture public reactions is by examining engagement with business‐like narratives in media.

Can Knowledge of Taxi Drivers’ Intentions to Commit Traffic Violations Predict Crash Frequency?
SafetyTaxi drivers are a group with high driving exposure and are involved in a significant number of urban traffic casualties. Using two modelling approaches, this study examines whether the intention to speed, as measured by the Theory of Planned Behaviour ...

Modelling Negative Binomial as a substitute model to Poisson for raters agreement on ordinal scales with sparse data [PDF]
, 2004 The Poisson distribution has been widely used for modelling rater agreement using loglinear models. Mostly in all life or social science researches, subjects are being classified into categories by rater, interviewers or observers and most of these ...

Oikos, EarlyView.Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

Oikos, EarlyView.Functional traits allow ecologists to synthesise general rules of community assembly. In joint species distribution modelling, traits are increasingly used to explain species–environment relationships, with the intention of being able to generalise predictions to other species in other systems.

Generalized Additive Models for Location Scale and Shape (GAMLSS) in R
Journal of Statistical Software, 2007 GAMLSS is a general framework for fitting regression type models where the distribution of the response variable does not have to belong to the exponential family and includes highly skew and kurtotic continuous and discrete distribution.
