Local Likelihood for Interval-censored and Aggregated Point Process Data
The use of the local likelihood method (Tibshirani and Hastie, 1987; Loader, 1996) in the presence of interval-censored or aggregated data leads to a natural consideration of an EM-type strategy, or rather a local EM algorithm. In the thesis, we consider local EM to analyze the point process data …

Estimating Non-homogeneous Intensity Matrices in Continuous Time Multi-state Markov Models
… which are less than ideal. We propose a local likelihood method, based on Tibshirani and Hastie (1987) and Loader (1996), to estimate the transition intensities as continuous functions of time. In particular the local EM algorithm suggested by Betensky et al. (1999) is employed to …

Model Robust Regression Based on Generalized Estimating Equations
… data. We combine a nonparametric method based on local estimation with a global, parametric generalized estimating equations (GEE) estimate through a mixing parameter on both the mean scale and the linear predictor scale. As a special case, when data are uncorrelated, this amounts to mixing a …

Prediction of parallel in-register amyloidogenic beta-structures In highly beta-rich protein sequences by pairwise propensity analysis
… structure prediction. BETASCAN calculates likelihood scores for potential beta-strands and strand-pairs based on correlations observed in parallel beta-sheets. The program then determines the strands and pairs with the greatest local likelihood for all of the sequence's potential …

Statistical modelling and variability of the subtropical front, New Zealand
… ocean fronts from AVHRR SST images. Weighted local likelihood is used to provide a nonparametric description of spatial variations in the position and strength of individual fronts within an image. Although we use the new algorithm on AVHRR data it is suitable for other satellite data or model …

Algorithms for enhanced spatiotemporal imaging of human brain function
… a harmonic basis for these artifacts, develop a local likelihood estimation algorithm to remove them, and demonstrate enhanced recovery of oscillatory and evoked EEG dynamics in the MRI scanner. Second, M/EEG source imaging offers a means to characterize rapidly evolving regional dynamics within …
