  1. 1. THE WELL-BEING OF ACADEMICALLY RESILIENT STUDENTS IN GERMANY Reanalysis of PISA 2015 data using Structural Equation Modeling

    University essay from Göteborgs universitet/Institutionen för pedagogik och specialpedagogik

    Author : Deborah Elin Siebecke; [2020-01-22]
    Keywords : Academic Resilience; Disadvantaged High-Achievers; Well-Being; Academic Performance;

    Abstract : Aim:This study aims at investigating the well-being of academically resilient students, as well as examining a possible effect of well-being on achievement. In doing so, this study attempts at contributing to a smaller research gap concerning the well-being of academically resilient students. READ MORE

  2. 2. Modeling asymmetry in volatility response - non-Gaussian innovations approach

    University essay from Lunds universitet/Statistiska institutionen

    Author : Ludvig Göransson; [2020]
    Keywords : ARCH; GARCH; APARCH; Asymmetric GARCH; non-Gaussian innovations; Laplace distribution; Leverage effect; Stylized facts; Volatility process.; Mathematics and Statistics;

    Abstract : This thesis is an explorative note on the non-Gaussian innovations of the volatility process. More specifically, the thesis investigates if the decomposition of the Standard Classical Laplace (SCL) distribution to a difference of two exponential is a valid alternative to modelling the asymmetric volatility processes, taking volatility clustering, the leverage effect and asymmetric response in volatility into account.

  3. 3. Machine Learning Based Prediction and Classification for Uplift Modeling

    University essay from KTH/Matematisk statistik; KTH/Matematisk statistik

    Author : Lovisa Börthas; Jessica Krange Sjölander; [2020]
    Keywords : Uplift Modeling; Data Pre-Processing; Predictive Modeling; Incremental Modeling; Random Forests; Logistic Regression; Neural Networks; Ensemble Methods; Machine Learning; Multi-Layer Perceptron; Inkrementell responsanalys; databehandling; prediktiv modellering; random forests; logistisk regression; neurala nätverk; mulit-layer perceptron; ensemble metoder; maskininlärning;

    Abstract : The desire to model the true gain from targeting an individual in marketing purposes has lead to the common use of uplift modeling. Uplift modeling requires the existence of a treatment group as well as a control group and the objective hence becomes estimating the difference between the success probabilities in the two groups.

  4. 4. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Chen Luo; [2020]
    Keywords : acid mine drainage; arsenic; cadmium; geochemical modeling; heavy metals; lead; principal component analysis;

    Abstract : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.

  5. 5. Sequence Prediction for Identifying User Equipment Patterns in Mobile Networks

    University essay from KTH/Matematisk statistik

    Author : Theoharis Charitidis; [2020]
    Keywords : Markov chain; mobile networks; user equipment; machine learning; statistics; sequence prediction; stochastic process; Maskininlärning; mobila nätverk; statistik; markovkedjor; all k order markov; stokastisk process; sekvensprediktering;

    Abstract : With an increasing demand for bandwidth and lower latency in mobile communication networks it becomes gradually more important to improve current mobile network management solutions using available network data. To improve the network management it can for instance be of interest to infer future available bandwidth to the end user of the network. READ MORE
