Extending the Dixon and Coles model: an application to women's football data
Rouven Michels, Marius Ötting, Dimitris Karlis
The prevalent model by Dixon and Coles (1997) extends the double Poisson model where two independent Poisson distributions model the number of goals scored by each team by moving p…
Optimal subdata selection for linear model selection
Vasilis Chasiotis, Dimitris Karlis
If the assumed model does not accurately capture the underlying structure of the data, a statistical method is likely to yield sub-optimal results, and so model selection is crucia…
On the selection of optimal subdata for big data regression based on leverage scores
Vasilis Chasiotis, Dimitris Karlis
The demand of computational resources for the modeling process increases as the scale of the datasets does, since traditional approaches for regression involve inverting huge data…
Subdata selection for big data regression: an improved approach
Vasilis Chasiotis, Dimitris Karlis
In the big data era researchers face a series of problems. Even standard approaches/methodologies, like linear regression, can be difficult or problematic with huge volumes of data…
