Recent studies show that soil animal count data are characterized by the presence of excess zeros and overdispersion, which violate the assumptions of standard statistical tests. Despite this, analyses have consisted of mainly non-parametric tests and log-normal least square regression (i.e. ANOVA). Failure to accommodate zero inflation in count data can result in biased estimation of ecologica...

An experiment in a mock-up office space gave occupants control over dimmable lighting circuits after a day working under pseudo-random lighting conditions. Data analysis indicated that the lighting experienced during the day influenced the changes in lighting made at the end of the day. Occupants chose to reduce screen glare if any existed. Even after allowing for the effect of glare, desktop i...

BACKGROUND The low (LF) vs. high (HF) frequency energy ratio, computed from the spectral decomposition of heart beat intervals, has become a major tool in cardiac autonomic system control and sympatho-vagal balance studies. The (statistical) distributions of response variables designed from ratios of two quantities, such as the LF/HF ratio, are likely to non-normal, hence preventing e.g., from ...

A typical task in statistical genetics is to find a sparse linear relation between genotypes with phenotypes, but often the data are confounded by age, ethnicity or population structure. We generalize the linear mixed model (LMM) Lasso approach for feature selection under confounding to the case of binary labels. This case is much more involved, as marginalization over the correlated noise lead...

An intelligent approach to autonomous land vehicle (ALV) guidance in outdoor road environments using combined line and road following and color information clustering techniques is proposed. Path lines and road boundaries are selected as reference models, called the line-model and the road-model, respectively. They are used to perform linemodel matching (LMM) and road-model matching (RMM) to lo...

Abstract Background Little attention has been paid to customising fatigue questionnaires for patients with Substance Use Disorders (SUDs). The present study aims validate and shorten the nine-item Fatigue Severity Scale (FSS-9) Visual Analogue (VAFS) use this population. Methods We used data from a nested cohort annual health assessments responses on FSS-9 VAFS. During period 2016–2020, 917 wer...

This paper compares the pricing and hedging performance of the LMM model against two spot-rate models, namely Hull-White and Black-Karasinski, and the more recent Swap Market Model from an Asset-Liability-Management (ALM) perspective. In contrast to previous studies in the literature, our emphasis here is on ALM and we use hedging performance on Bermudan swaptions to proxy risk management outco...

Anti-streptococcal antibodies cross-reactive with N-acetyl-betaD-glucosamine (GlcNAc) and myosin are present in the sera of patients with rheumatic fever (RF). However, their role in tissue injury is not clear. In this study, we show that anti-GlcNAc/anti-myosin mAb 3.B6 from a rheumatic carditis patient was cytotoxic for human endothelial cell lines and reacted with human valvular endothelium ...

The complexity of eye-movement control during reading allows measurement of many dependent variables, the most prominent ones being fixation durations and their locations in words. In current practice, either variable may serve as dependent variable or covariate for the other in linear mixed models (LMMs) featuring also psycholinguistic covariates of word recognition and sentence comprehension....

In this study, we investigated the biochemical basis for the induction of sialomucin production in HT-29 LMM human colon carcinoma cells. Previous studies showed that conditioned medium from organ cultures of normal human colonic connective tissues (NCCM) stimulated the biosynthesis of high molecular weight sialoglycoproteins (M(r) 740,000 and 450,000) by colon carcinoma cells in vitro. Using m...
