(1993). Weighted averaging partial least squares regression (WA-PLS): definition and comparison with other methods for species-environment calibration. ABSTRACT A multivariate calibration method is proposed that relates to correspondence analysis as partial least squares (PLS) relates to principal components analysis. The new method extends and improves the weighted averaging (WA) method for in...

PURPOSE To determine the relationship between different spectral domain optical coherence tomography (SD-OCT) signs of retinal ischemia in acute central retinal vein occlusion (CRVO) and whether they predict anterior segment neovascularization (ASNV). DESIGN Retrospective, observational study. SUBJECTS Thirty-nine consecutive patients with acute CRVO and 12 months of follow-up. METHODS We...

Automated image processing aids in classification of biological images. Many natural structures such as neurons may be multifractal and therefore not analyzable using current methods. The multifractal spectrum proposed here may mitigate this, Here we report the outcome of applying three methods that elucidate the variation within 16 rat retinal ganglion cells using the local connected fractal d...

This study aims to investigate the effects of violations of the sphericity assumption on Type I error rates for different methodical approaches of repeated measures analysis using a simulation approach. In contrast to previous simulation studies on this topic, up to nine measurement occasions were considered. Therefore, two populations representing the conditions of a violation vs. a non-violat...

The paper describes an application of a one class KNN to identify different signal patterns embedded in a noise structured background. The problem becomes harder whenever only one pattern is well-represented in the signal; in such cases, one class classifier techniques are more indicated. The classification phase is applied after a preprocessing phase based on a multi layer model (MLM) that pro...

OBJECTIVE To develop a general method for using the alerting function of an electronic health record (EHR) system to warn prescribers when a drug order may be in conflict with the restrictions of a patient's research protocol. METHODS We examined a sample of clinical research protocols at the National Institutes of Health (NIH) to identify the frequency with which drugs were excluded by proto...

Two series of reinfection experiments were carried out using C57BL mice. In the first series, the mice were inoculated with Mycobacterium lepraemurium (MLM) in one hind footpad and reinoculated in the contralateral footpad, two or four weeks later. Compared with normal mice of the same strain, the mice reinoculated after four weeks showed an increased local reaction to the bacilli and the bacil...

Three hundred 1-day old broiler chickens were used to assess the effects of Mucuna leaf meal (MLM) dietary supplementation on performance, haemato-biochemical indices, oxidative status and meat chickens. Five experimental supplemented diets formulated: diets: 1 (0% supplement), 2 (1.1 % OXYT), 3 (0.5% MLM), 4 (1.0 MLM) 5 (1.5% MLM). The final weight gain birds fed was higher (p < 0.05) than ...

OBJECTIVE This article reviews and compares four commonly used approaches to assess patient responsiveness with a treatment or therapy (return to normal (RTN), minimal important difference (MID), minimal clinically important improvement (MCII), OMERACT-OARSI [Outcome Measures in Rheumatology-Osteoarthris Reseach Society International] (OO)) and demonstrates how each of the methods can be formul...
