  1. 1. MODELING CAPITAL ASSET RETURNS ON THE SWEDISH STOCK MARKET - An evaluation of Fama French’s Five Factor Model against its predecessors

    University essay from Lunds universitet/Statistiska institutionen

    Author : Kristoffer Bergram; Ludvig Göransson; [2019]
    Keywords : asset pricing modeling; time series regression; statistics; Fama French Five Factor model; Carhart Four Factor model; Fama French Three Factor model; Swedish stock market; portfolio theory; behavioral economics; Mathematics and Statistics; Business and Economics;

    Abstract : This thesis compared the explanatory rate of three asset pricing models related to excess returns on the Swedish stock market. A more granular evaluation of each model’s factors was also conducted. A random sample of 90 companies was drawn from the Stockholm Stock Exchange (N = 371) using a Blomberg terminal. READ MORE

  2. 2. Approximation of Pi

    University essay from Lunds universitet/Matematik LTH

    Author : Madeleine Jansson; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The inverse tangent function can be used to approximate pi. When approximating pi, the convergence of infinite series or Products are of great importance for the accuracy in the digits in pi. This thesis will present historical Formulas used to approximate pi, especially Gregory-Leibniz and Machin's. READ MORE

    University essay from Lunds universitet/Matematisk statistik

    Author : Nathaniel Joselson; Rasmus Hallén; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : We have constructed a novel neural network architecture called CWE-LSTM (concatenated word-emoji bidirectional long short-term memory) for classify- ing emotions in Twitter conversations. The architecture is based on a combina- tion of word and emoji embeddings with domain specificity in Twitter data. READ MORE

  5. 5. On the statistics and practical application of the reassignment method for Gabor spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik. M Månsson; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. READ MORE
