  1. 1. Predicting the Impact of Supply Chain Disruptions Using Statistical Analysis and Machine Learning

    University essay from KTH/Matematisk statistik

    Author : Hannes Andersson; John Sjöberg; [2023]
    Keywords : Supply chain disruption; SMOTE; feature engineering; machine learning; random forest; statistics; applied mathematics; Störning i försörjningskedja; maskininlärning; matematik; statistik;

    Abstract : The dairy business is vulnerable to supply chain disruptions since large safety stocks to cover up losses are not always a viable option, therefore it is crucial to maintain a smooth supply chain to ensure stable delivery accuracies. Disruptions are unpredictable and hard to avoid in the supply chain, especially in cases where production errors cause lost production volume. READ MORE

  2. 2. Supervised classification for human movement data : A comparative study of functional and traditional methods

    University essay from Umeå universitet/Statistik

    Author : Markus Lindvall; [2023]
    Keywords : ;

    Abstract : Functional data analysis (FDA) has a growing importance in statistics, especially in disciplines like biomechanics, where it is common to observe data over time. The objective of this thesis is to employ FDA techniques and compare the classification performance of supervised classification models utilizing functional data with the same models using a discrete summary measurement (max-values) as input.

  3. 3. Counting Double-Descents and Double-Inversions in Permutations

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Jonas Boberg; [2021]
    Keywords : Combinatorics; Permutations; Permutation Statistics; Descent; Inversion;

    Abstract : In this paper, new variations of some well-known permutation statistics are introduced and studied. Firstly, a double-descent of a permutation π is defined as a position i where πi ≥ 2πi+1. By proofs by induction and direct proofs, recursive and explicit expressions for the number of n-permutations with k double-descents are presented. READ MORE

  4. 4. A permutation evaluation of the robustness of a high-dimensional test

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Nils Eckerdal; [2018]
    Keywords : 𝑛; 𝑝 -asymptotics; permutation test; U-statistics;

    Abstract : The present thesis is a study of the robustness and performance of a test applicable in the high-dimensional context (𝑝>𝑛) whose components are unbiased statistics (U-statistics). This test (the U-test) has been shown to perform well under a variety of circumstances and can be adapted to any general linear hypothesis. READ MORE
