1. 6. On Valuation of Observations in Linear Regression Models

   University essay from Lunds universitet/Statistiska institutionen

   Author : Mattias Jönsson; [2020]
   Keywords : Mathematics and Statistics;

   Abstract : In the Machine Learning field, more and more of the data collection is commercialised, even with monetary rewards to people and organisations for providing input data for models. Even if data collection is not associated with direct costs for the researcher, there are many cases where there are indirect, or circumstancial, costs associated with it. READ MORE

3. 7. Sales Modeling and Local Factor Decomposition for Optimal Investment Decisions in MMM: A Monte Carlo Simulation Study

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Daniel Heimgartner; [2020]
   Keywords : Marketing Mix Modeling; Shapley Value Regression; Time-Varying Effect Models; Shapley Additive Explanations; Accumulated Local Effects;

   Abstract : Media Mix Models (MMM) are used to understand drivers behind key performance indicators and to measure the effectiveness of media channels. The key metric to report causal impacts of media investments on sales is return on investment (ROI). The shape of ROI-curves crucially impacts optimal allocation. READ MORE

4. 8. Marketing Mix Modelling: A comparative study of statistical models

   Author : Olle Abrahamsson; [2017]
   Keywords : terrorists; hiding; network theory; social network; graph theory; eigenvector centrality; game theory; cooperative game; Shapley value; Myerson value;

   Abstract : In this thesis a known heuristic for decreasing a node's centrality scores while maintaining influence, called ROAM, is compared to a modified version specifically designed to decrease eigenvector centrality. The performances of these heuristics are also tested against the Shapley values of a cooperative game played over the considered network, where the game is such that influential nodes receive higher Shapley values.
