  1. 1. Evaluating probability weighting among lottery bond investors: an observational study on Cumulative Prospect Theory

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Anton Eriksson Nyberg; Olof de Blanche; [2024]
    Keywords : Cumulative Prospect Theory; CPT; observational study; field study; lottery bonds;

    Abstract : Cumulative Prospect Theory is a leading descriptive theory of decisions under uncertainty, backed up by a plethora of experimental evidence. This paper is one of the first to apply it to observational data. Risk attitudes in the bond market have not been studied in a CPT framework. We fill this research gap. READ MORE

  3. 2. An Empirical Investigation of The Effect of Proxy Response and The Merits of Its Remedial Measures

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Charles Edward Okon; Randi Kalanika Assalaarachchi; [2023]
    Keywords : missing data; proxy response; missingness mechanism; error-in-variable; logistic regression; Monte-Carlo simulation; missing at random; complete case analysis; proxy substitution; multiple imputation; inverse probability treatment weighting;

    Abstract : In the event of missing data, substitution of data from proxy sources are usually considered a very useful alternative when available to avoid the problem of missingness. Nonetheless, research has also shown that this approach often induces “response bias”. READ MORE

  4. 3. Evaluating Risk Factors with Regression : A Review and Simulation Study of Current Practices

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Ragna Reinhammar; [2022]
    Keywords : ;

    Abstract : The term ”risk factor” is used synonymously with both predictor and causal factor, and causal aims of explanatory analyses are rarely stated explicitly. Consequently, the concepts of explaining and predicting are conflated in risk factor research. READ MORE

  5. 4. Probability Distortion in the relationship between Depression and Problem Gambling: A Mediation Analysis

    University essay from Göteborgs universitet/Graduate School

    Author : Chi Nguyen; David Johansson; [2021-08-04]
    Keywords : problem gambling; depression; probability distortion; mediation; probability weighting function; prospect theory;

    Abstract : We posit that people with depressive symptoms are prone to problem gambling, and explore whether one possible driver of this is that depression increases misperception of probabilities. To test this hypothesis, we conducted a self-report survey on 230 regular gamblers recruited from Prolific. READ MORE

  6. 5. Inverse probability weighted generalised estimating equations for longitudinal data

    University essay from Lunds universitet/Matematisk statistik

    Author : Andrea Mattsson; [2021]
    Keywords : weighted generalised estimating equations; inverse probability weighting; longitudinal study; missing data; truncation by death; lung function; FEV1; Mathematics and Statistics;

    Abstract : Longitudinal study designs, in which variables of interest are observed at multiple time points in a study population, are frequently used in clinical research. Missing data are common in these types of studies. Moreover, in studies investigating a population where the mortality rate is high, data can be truncated by death. READ MORE
