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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ronnie Pingel; Uppsala universitet.; [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

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

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

    Author : Kristofer Månsson; Högskolan i Jönköping.; Högskolan i Jönköping.; [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.

  3. 3. 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; Umeå universitet.; [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

  4. 4. Economic studies of Green Commercial Buildings in Sweden

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Magnus Bonde; KTH.; [2013]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Climate change has risen to become one of our most critical global issues to resolve. Greenhouse gas emissions have been identified as one of the main causes for increased global temperature. As most energy production causes emission of greenhouse gases, a more energy efficient real estate sector could reduce the global greenhouse gas emissions. READ MORE

  5. 5. Towards efficient vehicle dynamics development From subjective assessments to objective metrics, from physical to virtual testing

    University dissertation from Stockholm : Kungliga tekniska högskolan

    Author : Gaspar Gil Gómez; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steering feel; vehicle handling; driver preference; objective metrics; subjective assessments; regression analysis; artificial neural network; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Vehicle dynamics development is strongly based on subjective assessments (SA) of vehicle prototypes, which is expensive and time consuming. Consequently, in the age of computer- aided engineering (CAE), there is a drive towards reducing this dependency on physical test- ing. READ MORE
