  1. 1. Analysing Regime-Switching and Cointegration with Hamiltonian Monte Carlo

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Jakob Brandt; [2023]
    Nyckelord :Time Series Econometrics; Regime-Switching; Cointegration; Markov Chain Monte Carlo; Hamiltonian Monte Carlo;

    Sammanfattning : The statistical analysis of cointegration is crucial for inferring shared stochastic trends between variables and is an important area of Econometrics for analyzing long-term equilibriums in the economy. Bayesian inference of cointegration involves the identification of cointegrating vectors that are determined up to arbitrary linear combinations, for which the Gibbs sampler is often used to simulate draws from the posterior distribution.

  3. 2. A Comparative Review of SMOTE and ADASYN in Imbalanced Data Classification

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Jakob Brandt; Emil Lanzén; [2021]
    Nyckelord :Machine learning; supervised learning; classification; class imbalance; over-sampling; SMOTE; ADASYN; Sensitivity; F-measure; Matthews correlation coefficient;

    Sammanfattning : In this thesis, the performance of two over-sampling techniques, SMOTE and ADASYN, is compared. The comparison is done on three imbalanced data sets using three different classification models and evaluation metrics, while varying the way the data is pre-processed. LÄS MER

  5. 4. Time, Rationality and at least three kinds of Reason

    Kandidat-uppsats, Lunds universitet/Praktisk filosofi

    Nyckelord :Philosophy; Time; Rationality; Bias towards the near; Bias towards the future; Ideals; Ingmar Persson; Derek Parfit; Philosophy and Religion;

    Sammanfattning : All too often we find ourselves choosing a lesser good instead of a greater good, due to the mere fact that the lesser good is closer in the future, and all too often we find ourselves preferring that greater suffering has happened in the past rather than us having to experience small suffering in the future. Philosophers call this phenomena time biases, the first bias is called the bias towards the near and the second one is called the bias towards the future. LÄS MER
