In this paper fading correlation of α-μ distribution considering multi-antenna receiver is discussed. Diversity combining techniques are briefly outlined. Correlation coefficient and joint probability density function for alpha-mu fading is shown. Generalized correlation coefficient for two alpha-mu fading variates is defined. Simulation results of outage and Bit Error Rate (BER) for different ...

Montero et al. do report the 95% limits on the Bland-Altman plot, perhaps the authors could have reported the 95% limits of agreement for a specific number of thresholds of proteinuria for example <300mg, <3.5 grams or >3.5 grams individually which would be useful for clini-cians trying to interpret spot urine pro-tein/creatinine ratio. I worry that readers of this excellent study may be left f...

A nonparametric EM (NPEM) algorithm for population pharmacokinetic modeling has been implemented as a computer program for the IBM PC and compatible machines. It computes the joint probability density function (PDF) for a 1 compartment pharmacokinetic model with intravenous dosing. It can operate using data of only one serum level per patient. The program utilizes patient data files from the US...

Judged association between two variables represented on scatterplots increased when the scales on the horizontal and vertical axes were simultaneously increased so that the size of the point cloud within the frame of the plot decreased. Judged association was very different from the correlation coefficient, r, which is the most widely used measure of association.

The objective of this study is to evaluate the capability of satellite imagery for the estimation of basal area in Northern Zagros Forests. The data of the high resolution geometric (HRG) sensor of SPOT-5 satellite dated in July 2005 were used. Investigation of the quality of Satellite images shows that these images have no radiometric distortion. Overlaying of geocoded images with the digital ...

The well-known fact that Pearson’s product-moment correlation coefficient between two variables is the cosine of the angle between the centered variable profiles suggests a way to visualize correlation. This angular representation of product-moment correlation is automatically displayed in an h-plot. Using ideas from multidimensional scaling, an alternative angular representation of correlation...

Results Of 166 trials, only 56 (34%) reported all key elements of sample size calculations in line with CONSORT recommendations. Elements specific to CRTs were the worst reported: the number of clusters or average cluster size was specified in only 94 (57%) and a measure of intracluster correlation coefficient (ICC) in only 86 (52%). Only 20 papers (12%) reported a priori and observed ICC value...

STUDY DESIGN Prospective multicenter trial. SETTING Seventeen otorhinolaryngological centers. SUBJECTS AND METHODS Data are part of the Scandinavian Bell's palsy study. The facial function of 1920 patients with peripheral ...
