  4. 3. Fisher Inference and Local Average Treatment Effect: A Simulation study

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Iveta Tvaranaviciute; [2020]
    Nyckelord :Randomized experiments; noncompliance; two-stage least squares; weak instruments; Fisher Randomization Test; Neyman-Pearson; statistical power;

    Sammanfattning : This thesis studies inference to the complier treatment effect denoted LATE. The standard approach is to base the inference on the two-stage least squares (2SLS) estimator and asymptotic Neyman inference, i.e., the t-test. LÄS MER

  5. 4. Fisher's Randomization Test versus Neyman's Average Treatment Test

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Kajsa-Lotta Georgii Hellberg; Andreas Estmark; [2019]
    Nyckelord :Nonparametric; Parametric; Monte Carlo Approximation; Inference;

    Sammanfattning : The following essay describes and compares Fisher's Randomization Test and Neyman's average treatment test, with the intention of concluding an easily understood blueprint for the comprehension of the practical execution of the tests and the conditions surrounding them. Focus will also be directed towards the tests' different implications on statistical inference and how the design of a study in relation to assumptions affects the external validity of the results.

  7. 5. 5G Positioning using Machine Learning

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Magnus Malmström; [2018]
    Nyckelord :5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

    Sammanfattning : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.
