  1. 16. Confounder Parsing for Text Matching

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Jannes Reichl; Johan Rönkkö; [2021-07-06]
    Nyckelord :Text matching; confounder parsing; causal inference; covariate balance; International Monetary Fund; policy evaluation;

    Sammanfattning : In observational studies for policy evaluation, matching is used in service of causal inference to simulate randomization and thus reduce selection bias that might occur when treatment assignment differs systematically. This is done by balancing the distribution of confounding covariates measured before treatments. LÄS MER

  3. 17. Association between cognitive measures, global brain surface area, genetics, and screen-time in young adolescents : Estimation of causal inference with machine learning

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Evgenija Kravchenko; [2021]
    Nyckelord :Causal modelling; DirectLiNGAM; PGS; intelligence; screen time; cognitive development; Kausal modellering; DirectLiNGAM; PGS; intelligens; skärmtid; kognitiv utveckling;

    Sammanfattning : Screen media activity such as watching TV and videos, playing video games, and using social media has become a popular leisure activity for children and adolescents. The effect of screen time has been a highly debated topic; however, there is still very little known about it. LÄS MER

  4. 18. The Impact of COVID-19 Restrictions on Air Quality- Based on Seven Cities in China

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Cheng Chen; [2021]
    Nyckelord :COVID-19; air quality; fixed effect model; regression discontinuity; Business and Economics;

    Sammanfattning : Many researchers have studied the impact of the COVID-19 restrictions. However, in terms of the air quality impact, few studies have done so for specific cities. In this study, seven cities in China under the first stage of transmission prevention have been selected. The air quality standard indicators discussed are NO2 (Nitrogen dioxide), PM2. LÄS MER

  5. 19. Causal discovery in conditional stationary time-series data : Towards causal discovery in videos

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carles Balsells Rodas; [2021]
    Nyckelord :Causality; Causal discovery; Neural networks; Graph neural network; Time series; Non-stationary; Orsakssamband; Kausal upptäckt; Neurala nätverk; Diagram Neurala nätverk; Tidsföljder; Icke-stationär;

    Sammanfattning : Performing causal reasoning in a scene is an inherent mechanism in human cognition; however, the majority of approaches in the causality literature aiming for this task still consider constrained scenarios, such as simple physical systems or stationary time-series data. In this work we aim for causal discovery in videos concerning realistic scenarios. LÄS MER

  7. 20. Estimating Causal Effects Of Relapse Treatment On The Risk For Acute Myocardial Infarction Among Patients With Diffuse Large B-Cell Lymphoma

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Jakob Börsum; [2021]
    Nyckelord :Causal Inference; Survival; Analysis; Marginal Structural Model;

    Sammanfattning : This empirical register study intends to estimate average causal effects of relapse treatment on the risk for acute myocardial infarction (AMI) among patients with Diffuse B-Cell Lymphoma (DLBCL) within the potential outcome framework. The report includes a brief introduction to causal inference and survival anal- ysis and mentions specific causal parameters of interest that will be estimated. LÄS MER
