1. 11. The Effect of Immigration on Income Distribution : A Comparative Study of Ordinary Least Squares and Beta Regression

   Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Fanni Forslind; [2021]
   Nyckelord :Ordinary least squares OLS ; Beta regression; Proportion dependent variable; Gini coefficient; Income distribution; Immigration;

   Sammanfattning : The purpose of this study is to estimate the relationship between income inequality and immigration in Sweden. To do so, data from the data base Kolada with observations from all 290 municipalities in Sweden is used. LÄS MER

3. 12. Geographically Weighted Regression based Investigation of Transport Policies for Increased Public Transport Ridership : A Case Study of Stockholm

   Master-uppsats, KTH/Transportplanering

   Författare :Robert Günther Klar; [2021]
   Nyckelord :Public transport competitiveness; Geographically weighted regression; Public transport usage rate; Feature selection; Predictive modelling; Smart card data; ollektivtrafikens konkurrenskraft; Geografiskt viktad regression; Public transport usage rate; förutsägande modellering; variabel val; Smart card data;

   Sammanfattning : Public transport plays a vital role in society as the economy, the degree of sustainability and the qualityof life of a city is directly affected by transportation. A shift in modal share towards public transport isassociated with many benefits such as increased air quality and improved space allocation within thecity. LÄS MER

4. 13. A forecasting approach to estimating cartel damages : The importance of considering estimation uncertainty

   Magister-uppsats, Södertörns högskola/Nationalekonomi

   Författare :Didrik Prohorenko; [2020]
   Nyckelord :Forecasting approach; estimation uncertainty; merger simulation; cartels; t-test; small sample size; damages; counterfactual analysis;

   Sammanfattning : In this study, I consider the performance of simple forecast models frequently applied in counterfactual analysis when the information at hand is limited. Furthermore, I discuss the robustness of the standard t-test commonly used to statistically detect cartels. LÄS MER

5. 14. On Valuation of Observations in Linear Regression Models

   Kandidat-uppsats, Lunds universitet/Statistiska institutionen

   Författare :Mattias Jönsson; [2020]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : In the Machine Learning field, more and more of the data collection is commercialised, even with monetary rewards to people and organisations for providing input data for models. Even if data collection is not associated with direct costs for the researcher, there are many cases where there are indirect, or circumstancial, costs associated with it. LÄS MER

7. 15. The economic logic behind the creation of the Eurasian Economic Union: A gravity model estimation

   Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Vladislav Kaim; [2020]
   Nyckelord :post-Soviet space; Eurasian integration; Eurasian Economic Union; gravity model; trade flows; Business and Economics;

   Sammanfattning : This paper estimates the impact of the processes of the Eurasian integration in the post-Soviet space that led to the creation of the Eurasian Economic Union (EEU) in 2015 over the exports of the member countries and their main partners outside the EEU and its predecessor, the Customs Union (CU). Applying the gravity model technique over the dataset for 1995-2015 obtained from UNESCAP Trade Analytics, it is possible to determine the influence of the CU membership of both exporter and importer countries over the exports of the former after controlling for all the economic, cultural and logistical independent variables and two different types of estimation (OLS and Poisson estimator).
