  1. 1. Some Aspects of Propensity Score-based Estimators for Causal Inference

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ronnie Pingel; Johan Lyhagen; Theis Lange; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; correlation; treatment effect; inverse probability weighting; local linear estimator; matching; multicollinearity; observational study.; Statistics; Statistik;

    Abstract : This thesis consists of four papers that are related to commonly used propensity score-based estimators for average causal effects.The first paper starts with the observation that researchers often have access to data containing lots of covariates that are correlated. READ MORE

  3. 3. Issues of multicollinearity and conditional heteroscedasticy in time series econometrics

    University dissertation from Jönköping : Jönköping University, Jönköping International Business School

    Author : Kristofer Månsson; Ghazi Shukur; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This doctoral thesis consists of four chapters all related to the field of time series econometrics. The main contribution is firstly the development of robust methods when testing for Granger causality in the presence of generalized autoregressive conditional heteroscedasticity (GARCH) and causality-in-variance (i.e. spillover) effects.

  4. 4. Latent variable based computational methods for applications in life sciences Analysis and integration of omics data sets

    University dissertation from Umeå : Kemi

    Author : Max Bylesjö; Johan Trygg; Tormod Naes; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; orthogonal projections to latent structures; OPLS; O2PLS; K-OPLS; kernel-based; non-linear; regression; classification; Populus; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : With the increasing availability of high-throughput systems for parallel monitoring of multiple variables, e.g. levels of large numbers of transcripts in functional genomics experiments, massive amounts of data are being collected even from single experiments. READ MORE

  5. 5. Essays on Panel Data with Multidimensional Unobserved Heterogeneity

    University dissertation from Lund University (Media-Tryck)

    Author : Yana Petrova; [2020]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Econometrics; Factor-Augmented Panel Regression; Interactive Effects; Unknown Factors; CCE Estimation; Principal Components;

    Abstract : This thesis contributes to econometric methodology in terms of estimation and inference in static panel data models with unobserved multidimensional heterogeneity. When not properly accounted for, unobserved heterogeneity may introduce bias into the parameter estimates associated with covariates of interest, such as treatment indicators or determinants of macroeconomic indicators.
