Causal inference with time-series cross-sectional data : with applications to positive political economy
… sciences. Researchers often rely on two-way fixed effect models to estimate causal quantities of interest with TSCS data. However, they face the challenge that such models are not applicable when the so called "parallel trends" assumption fails, that is, the average treated counterfactual and …

Evaluation of genomic prediction models that incorporates peak GWAS signals in maize and sorghum diversity panels
… complex and thus governed by many genes of small effect. The statistical models typically used in a genome-wide association study (GWAS) and genomic selection (GS) quantify the contributions of genomic markers in linkage disequilibrium with these genes to trait variation. In general, the GWAS has …

Homeowner Views on Housing Market Valuation of Energy Efficiency: An Empirical Investigation
… of the home. In order to limit the impact of fixed housing characteristics on the model, the fixed effect regression technique is used. Empirical estimation provides evidence that homeowners feel the housing market assigns very limited value to the energy efficiency of their homes.

The effect of capital structure on profitability of manufacturing companies in Tanzania
This study analyzed the effect of capital structure on profitability of listed manufacturing companies in Tanzania using panel data of six companies listed in the Dar es Salaam Stock Exchange during a 5 year period. The period was from 2009 to 2013 in which 30 observations were obtained. Panel data …

The Economic Impacts of Forest Timber Methods in Washington State: a Hedonic Approach
… </strong> I estimate two sets of hedonic fixed effect regression models to control for omitted variable bias and spatial autocorrelation. The results show statistically significant impacts on property values for both cutting methods, adding important information for forest managers.

Subjective well-being in the European Union = Szubjektív jólét az Európai Unióban
… indicators within the European Union. We used fixed effect panel and difference models for estimations. The used method makes it possible to analyze the well-being effect of historical events like the euro adaptation or the EU accession from the subjective well-being point of view.

An analysis of the impact of capital structure on the financial performance of firms listed on the Namibian stock exchange
… employed panel data regression with pooled, fixed effect and random effect regression. Among the three methodologies, this study found that random effect regression is more appropriate to understand the proposed relationships in model 1 (return on equity) and model 2 (return on assets) in …

Three Essays on Worker Displacement
Chapter 1 examines the effect of job displacement on the distribution of earnings. I utilize a novel technique, quantile fixed effect regression, in order to examine how the overall distribution of earnings changes while controlling for unobserved heterogeneity in worker quality. I find that while …

A spatial analysis of corn and soybean yields and weather relations
… statistical models were tested, including two fixed effect models and one geographically weighted regression. Due to different underlying assumptions and specifications of each model, results indicated different implications. Major findings included severe weather conditions during plant.s …

Evaluation of spatial prediction methods for selected soil properties to support land suitability mapping for rice in Zambia.
… linear unbiased predictor (EBLUP) with the only fixed effect a constant mean performed better than the other methods used for predicting soil pH and the EBLUP with fixed effect performed better than other methods used for predicting soil organic carbon and soil Phosphorus. Random forests had the …
