Nonparametric efficient estimation of prediction error for incomplete data models
… assessment of predictions made in terms of predicted probabilities <br>that are coming from a regression model or other sources. <br> <br>This thesis is on defining and estimating measures of prediction error <br>based on the Brier score. Function valued parameters are introduced <br>which …

Addressing two issues in machine learning : interpretability and dataset shift
… This is a decision list classifier where the predicted probabilities are decreasing down the list. Experiments show that the gain in interpretability need not be accompanied by a large sacrifice in accuracy on real world datasets. I then briefly discuss possible extensions that allow one to …

Parametric modeling of dependence of bivariate quantile regression residuals' signs
… predictor. Both are conceived to constrain the predicted probabilities to lie within the feasible range. The estimated probabilities can be tested against the values of largest possible dependence and independence. The method permits to capture important aspects of the dependence of multivariate …

The impact of married women's employment on household expenditures for clothing
… the data included: (1) probit analysis to obtain predicted probabilities of wives’ labor force participation; (2) tobit analysis to predict wives’ wage rates; (3) tobit analyses of six separate clothing expenditure models that contained predicted values from (1) and (2); and (4) tobit analysis of …

Studying the Impact of First-Year Seminar Completion on First-Generation Academic Success
… utilized OLS regressions, logit regressions, and predicted probabilities to examine the effects of first-year seminar completion on four elements of academic success of the firstgeneration student population: first-year grade point averages, first to second-year retention, four-year graduation …

An Economic Analysis of Evolving Health Hazards
… risk or hazard maps that visually depict the predicted probabilities of human WNV and the standardized morbidity ratios. The predicted probabilities were generated from the IV spatial filtering random effects negative binomial model. The hazard maps may ultimately assist policy makers in …

On Mass Media, State Capacity, And Civil Conflict
… from 1993 to 2004. Over a series of models, predicted probabilities estimations, and a controlled experiment, I determine two novel findings: 1) mass media significantly impacts the likelihood of civil conflict under certain conditions and 2) the state capacity literature's objective …

Examining Racial and Ethnic Disparity in Prosecutor’s Bail Requests and Downstream Decision Making
… of regression modeling and analysis of predicted probabilities, and viewed through the lens of cumulative disadvantage theory, this study demonstrates that the effects of race and ethnicity vary by decision point and charge. Black defendants were found to have higher bail requests and …

Predictive Habitat Model for the Snapping Shrimp Genus <i>Alpheus</i> in the Coastal Southeastern United States
… and Shepard code and distance to shore). The predicted probabilities of snapping shrimp absence were comparable to those found in the training data set for the Gulf of Mexico. The AUC indicated that the best model built on the Gulf of Mexico training data set was not able to predict snapping …

Three Essays on Corporate Governance and CEO Dismissal
… show that firms managed by CEOs with high ML-predicted dismissal probabilities underperform, yielding positive and significant monthly abnormal returns. These firms also exhibit deteriorating future accounting performance, measured by industry-adjusted ROA, suggesting that ML models …

Evaluation of a Screening Battery for Developmental Language Disorder
… were then used to determine what measures predicted DLD. Predicted probabilities from the logistic regressions were entered into ROC curve analyses to analyze diagnostic accuracy of various models. Results of the dominance analysis revealed that sentence repetition was the most dominant …

Selection Bias In Lung Allocation: Influence On Lung Allocation Score And Physician Decision-Making
… for selection bias can lead to inaccurate predicted probabilities and suboptimal organ allocation. The goal of this dissertation is to improve the predictive accuracy of the LAS by mitigating selection bias so that lungs are allocated to the appropriate patients in the appropriate order. …

Markers and outcome measures in chronic immune mediated artrhritis: from association studies to prediction models.
… epitope testing are explored by different (predicted) probabilities plots, based on logistic regression. They demonstrate that combined ACPA and continuous RF-testing is the most relevant combination. In part 3, different single clinical measures and composite indices to measure response to …

Thrown off Course: School Suspension and Its Consequences for Students’ Educational Trajectories and Outcomes
… youths’ trajectories of engagement in school. Predicted probabilities are then calculated to determine how suspension interacts with race/ethnicity, socioeconomic status, and disability status to predict students’ educational development. Finally, structural equation modeling is used to examine …

Computer modelling of metabolic adaptions during mitochondrial dysfunction and machine learning to predict novel mitochondrial disease genes
… simulations of complex III inhibition accurately predicted many of the metabolite behaviours identified in the metabolomics analyses and provided theories for their significance. Simulations of the other complexes’ inhibitions identified many unique behaviours which can be used to direct future …

Intensive development of New Zealand’s indigenous grasslands: Rates of change, assessments of vulnerability and priorities for protection
… for the final model were used to map conversion probabilities in geographic space. The selected GAMs showed the mean probability of conversion in remaining indigenous grasslands was 0.15 and the mean area of conversion was 116 ha. Habitat that was most vulnerable to conversion was at moderate …

Dynamics of firm-level export diversification in Botswana
… adopted. This technique is used to estimate the predicted probabilities of moving between different product-destination categories as a firm grows in export value. The results reveal nonlinearities in the evolution of a firm’s diversification path. At low values of exports, firms concentrate on …

Descending Locomotion in Primates
… foot and limb proportions greatly affected the predicted probabilities of headfirst descent. Large primates with lower intermembral indices and smaller feet were least likely to use headfirst, especially as supports became more steeply angled. Species that were smaller, with relatively longer …

A Logistic Regression Analysis of Utah Colleges Exit Poll Response Rates Using SAS Software
In this study I examine voter response at an interview level using a dataset of 7562 voter contacts (including responses and nonresponses) in the 2004 Utah Colleges Exit Poll. In 2004, 4908 of the 7562 voters approached responded to the exit poll for an overall response rate of 65 percent. Logistic …
