Three essays on the UK Electricity Market: Risk Premium,Uncertainty of Supply and Forecasting
… Phase Shift (MOPS) to filter the data into trend and residual, and then forecasts for the trend and residual are generated separately and later combined. The proposed method for trend estimation performs better in terms of providing electricity day-ahead price forecasts as compared to some …

Comparison of Trend Detection Methods
Trend estimation is important in many fields, though arguably the most important applications appear in ecology. Trend is difficult to quantify; in fact, the term itself is not well-defined. Often, trend is quantified by estimating the slope coefficient in a regression model where the response …

A Smoothing Model and Its Asymptotics with Applications to Health Studies and Social Research
… The smoothing cohort model yields consistent estimation of age and period effects, but cohort effect estimation is biased. Hence, the second stage model aims to correct the bias by setting a constraint using the consistent estimation of age or period effect from the first stage. Selection of …

Teaching Facial Emotion Recognition to Low-Functioning 4-7 Year Old Students with Autism
… Visual analysis, use of the split-middle trend estimation, and statistical analysis all indicate that there was minimal change resulting from the intervention for Students 1 and 3. The results from Student 2 demonstrated minimal involvement in the Baseline or Intervention Phase activities. …

Identification of singularities in the displacement field for damage detection in structures
… In order to obtained reasonable slope change, a trend estimation for denoising purpose is needed. The Deflection-Wavelet approach locates the damage with a localization index based on the normalized wavelet coefficient for different scales and estimates the damage with a quantifi-cation index …

Remote sensing of croplands, crop productivity, and water use efficiency with a focus on smallholder systems in southern Africa
… However, more accurate mapping of croplands, estimation of crop productivity, and monitoring of production trends are required. Accommodating the dynamic, seasonal nature of farming systems in mapping and productivity models, and production trend monitoring methods, may enhance their accuracy. …
