Calibration Efficacy of Three Logistic Models to the Degrees of Reading Power Test Using Residual Analysis
The publisher of the Degrees of Reading Power test of reading comprehension (DRP) calibrate their test using an item response model called the Rasch or one-parameter logistic model. The relationship between the use of the Rasch model in calibration of the DRP and the use of the DRP as a component …

Landscape patterns and patch dynamics in Hamilton county over a forty year period: applicability to the conservation of the eastern box turtle
… global and local autocorrelation statistics and residual analysis of ordinary least squares (OLS) and geographically weighted regression (GWR) models using core as dependent variable and area, perimeter and mean slope as independent variables. Increasing fragmentation and road density over time …

A generic fault detection and diagnosis approach for pneumatic and electric driven railway assets
… fault diagnosis methods using fault model and residual analysis are proposed and the fault model based fault diagnosis is preliminarily approached. Finally, a new three level architecture for railway condition monitoring is discussed for practical applications.

Benchmarking Residential Electricity Consumption: A Utility’s Machine Learning Approach to Smart Metering Data and the European Energy Crisis
… identifiable information. We also perform residual analysis to identify households that are most sensitive to changes in temperature. This creates a strong foundation for demand-response with customers. As Europe heads towards a long-term energy crisis, it is crucial that utilities have a …

Pavement Resilience Assessment Using Pavement Condition Data Before and After Hurricane Harvey
… before and after the event. Regression analysis identified pre-Harvey condition score and pavement type as significant predictors of a post-Harvey condition. Random Forest model analyzed the distress-specific patterns across the pavement types followed by residual analysis which further …

Agricultural Trade Performance and Potential: A Retrospective Panel Data Analysis of US Exports of Corn and Soybeans
… pseudo maximum likelihood (PPML) estimations. Residual analysis is used to assess the difference between actual trade and the trade levels predicted by the models. The results suggest that anti-GMO policies reduce trade values by an average of 11%. The largest difference between predictions and …

PSO modelling and PID controlled of automatic fish feeder system
… ARX model parameter. Validation tests used was residual analysis. The best transfer function was then used as a modelling plant in the simulation process with PID controller to determine the optimum PID parameters. Finally, implementation of a PID controller into real time system was done to …

The impact of selected dividend announcements on daily stock returns
… and (6) dividend omissions. A standard daily residual analysis is conducted for each sample using four different sets of estimates for expected returns. Performance indicies are computed for the forty-one days symmetric to the announcement date and tests of significance are provided. The …

Synthesis of Local Thermo-Physical Models Using Genetic Programming
… is automated through principal component analysis and heuristics. For each candidate model, the model parameters are optimized in the inner integrated nested loop. The trade-off between accuracy and model complexity is addressed through incorporation of the Minimum Description Length (MDL) …

Body composition of dogs determined by carcass composition analysis, deuterium oxide dilution, subjective and objective morphometry, and bioelectrical impedance
… regression techniques. Influence diagnostics, residual analysis and data splitting were used to validate predictive equations. Predictions from deuterium oxide dilution produced the most precise estimates of body composition. Average standard errors of estimation (SEE) from deuterium equations …

Synchronization, Variability, and Nonlinearity Analysis: Applications to Physiological Time Series
… study synchronization, variability, nonlinearity analysis and their applications in physiological time series. For synchronization analysis, we explore both intensity and directionality of interaction. We propose a computational method to specify frequency ratio n : m, detect the moment when the …

Essays on Financial Crises in Emerging Markets: Role of Capital Inflow, Financial Intermediaries and the Dynamics of Contagion
… account movements in fundamentals. Regression analysis shows that own-country news and other fundamentals had substantial impact on the markets. However, residual analysis shows that after controlling for fundamentals, there remains substantial cross-border correlation in the financial markets. …

A survey of children's beliefs, expectations and preferences about the consequences of disclosing intrafamilial abuse
… in qualitative interviews was conducted. Content analysis of these answers were used to compile a questionnaire which was administered to 489 children by locally trained fieldworkers. The questionnaire contained questions pertaining to demographics, health, social support, and closed-ended Likert …
