This paper briefly reviews the most frequently used and misused intraclass correlation analysis of variance (ANOVA) reliability measures. Recommendations are made for the one-way ANOVA intraclass correlation and against the use of several coefficients: Winer's so-called "anchor point method," KuderRichardson Formula Number 20, and the Spearman-Brown prediction formula. The computation of the in...

Spearman’s rank correlation coefficient is a nonparametric (distribution-free) rank statistic proposed by Charles Spearman as a measure of the strength of an association between two variables. It is a measure of a monotone association that is used when the distribution of data makes Pearson’s correlation coefficient undesirable or misleading. Spearman’s coefficient is not a measure of the linea...

BACKGROUND Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) allows selective replacement of the endothelium. Post-operative haze and particles can affect the interface quality and, ultimately, visual outcome. In this study, we evaluated DSAEK interface with in vivo laser confocal microscopy (LCM) in order to: (i) correlate interface status with best corrected visual acuity, and (ii...

Method Current research comprised of histo-morphometrical study of 120 skin samples collected in horizontal and vertical orientations from anterior chest area and lateral chest areas of formalin embalmed human cadavers (n = 30). The quantitative fraction of dermal collagen and elastic fiber content was obtained by tissue-quant image analysis. Spearman correlation coefficient (r) was computed to...

Nuclear receptors are necessary for uterine invasion of the trophoblast and therefore important for maintaining a viable pregnancy. The aim of this study was to investigate the expression pattern and frequency of LXR, PPARγ and RXRα under physiological circumstances and in spontaneous abortions in endometrial glands and decidual tissue cells. A total of 28 (14 physiologic pregnancies/14 spontan...

OBJECTIVE To determine the concurrent validity of the Balance Outcome Measure for Elder Rehabilitation (BOOMER) with both the Berg Balance Scale (BBS) and gait speed. DESIGN Prospective cohort study. SETTING Two geriatric rehabilitation units. PARTICIPANTS Elderly adults (N=134) admitted to inpatient rehabilitation. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The BOOMER consis...

Moyamoya patients underwent cerebral revascularization surgery had higher risk for postoperative complications. Cerebral autoregulation impaired may be the main mechanism for postoperative complications. In our study, we used correlation coefficient r between cerebral tissue oxygenation index (TOI) and mean arterial blood pressure (MAP) to assessing of cerebral autoregulation. Total 30 moyamoya...

A composite collaborative filtering algorithm for personalized recommend will be presented to solve the original Collaborative Filtering algorithm problem including“None of User Starting ”and “Data Sparsity”, and the Spearman rank correlation coefficient will be used as a main correlation coefficient. Top-M commended is going to be used to get the final results in this paper. At last, we will v...

Use the method of spearman correlation analysis and dynamic clustering to delete indicators and build an evaluation index system of the green industry. The specialties and contributions of this paper lie in three aspects. Firstly, screen indicators according to the different effects on the clustering results of the evaluation objects from having or not having specific indicators, and delete the...
