  1. 21. The Quest for Robust Model Selection Methods in Linear Regression

    Author : Prakash Borpatra Gohain; Magnus Jansson; K.V.S Hari; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model selection; information criterion; linear regression; sparsity; high dimensional; Electrical Engineering; Elektro- och systemteknik; Mathematical Statistics; Matematisk statistik;

    Abstract : A fundamental requirement in data analysis is fitting the data to a model that can be used for the purpose of prediction and knowledge discovery. A typical and favored approach is using a linear model that explains the relationship between the response and the independent variables. READ MORE

  2. 22. Observational Uncertainties in Water-Resources Modelling in Central America : Methods for Uncertainty Estimation and Model Evaluation

    Author : Ida Westerberg; Sven Halldin; Jan Seibert; Lars-Christer Lundin; Chong-Yu Xu; Deliang Chen; Alberto Montanari; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE

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

    Author : Max Bylesjö; Johan Trygg; Tormod Naes; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; orthogonal projections to latent structures; OPLS; O2PLS; K-OPLS; kernel-based; non-linear; regression; classification; Populus; Chemistry; 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. 24. Essays on Empirical applications of Real Estate Economics and Finance

    Author : Mo Zheng; Han-Suck Song; Mats Wilhelmsson; Fredrik Armerin; Shahiduzzaman Quoreshi; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Real Estate Economics and Finance; Hedonic regression; Spatial econometrics; Residential market; Housing index; GARCH; Volatility forecasting; COVID-19; Value-at-Risk; Extreme Value Theory; Fastighetsekonomi och finans; Hedonisk regression; Spatial ekonometri; Bostadsmarknad; Bostadsindex; GARCH; Volatilitetsprognoser; COVID-19; Value-at-Risk; Extreme Value Theory; Fastigheter och byggande; Real Estate and Construction Management;

    Abstract : This doctoral thesis is a collection of four essays that utilize cross-sectional and time-series econometric methods in real estate economics and finance. The first two essays apply econometric modeling to the residential market focusing on hedonic regression analysis, while the other two essays apply financial econometric modeling on an index of listed real estate stocks, and house price index indices.

  5. 25. Towards prediction in ungauged aquifers – methods for comparative regional analysis

    Author : Ezra Haaf; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Prediction in ungagued aquifers; Comparative hydrogeology; Similarity; Groundwater hydrographs; Groundwater dynamics; Time series clustering; Groundwater climate interaction; Classification; Regression; Groundwater storage; Groundwater resources management;

    Abstract : Hydrogeological investigations and in particular groundwater resource assessments are strongly reliant on understanding the factors controlling groundwater level dynamics. However, historical records of measured groundwater levels are often scarce and unevenly distributed in space and time. READ MORE
