conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...

Improving the detection of relevant variables using a new bivariate measure could importantly impact variable selection and large network inference methods. In this paper, we propose a new statistical coefficient that we call the rank minrelation coefficient. We define a minrelation of X to Y (or equivalently a majrelation of Y to X) as a measure that estimate p(X ≤ Y ) when X and Y are continu...

Correlation mining is an approach of drawing statistical relationship between items from transaction data. Most of the existing techniques use Pearson’s correlation coefficient as a measure of correlation, which may not always perform well when data are noisy and binary in nature. Moreover, they require multi-pass over the database. This paper presents an effective and faster correlation mining...

TO THE EDITOR—Jarvis et al describe the evaluation of a point-of-care antigen test for cryptococcal meningitis against a quantitative sandwich enzyme-linked immunosorbent assay using the Spear-man rank correlation coefficient [1].

Comparisons of automatic evaluation metrics for machine translation are usually conducted on corpus level using correlation statistics such as Pearson’s product moment correlation coefficient or Spearman’s rank order correlation coefficient between human scores and automatic scores. However, such comparisons rely on human judgments of translation qualities such as adequacy and fluency. Unfortun...

introduction: teachers’ evaluation is one of the most important factors in decision making in university. it is done to determine the situation of  teaching activities. since the university rank in comprehensive exam of basic sciences(cebs) is indicated as educational success, this survey was carried out to determine the relationship between university ranks of  cebs in different courses and th...

Methods We selected 120 consecutive patients who underwent transperineal fusion-biopsy before RP. All men received a saturation biopsy (SB) in addition to targeted biopsies of lesions with PIRADS≥2. On RP specimen, the index lesion was defined as highest Gleason score (GS) or highest tumour volume (TV). GS=3+3 and TV≥1.2ml or GS=3+4 and TV≥0.7ml or GS>3+4 were considered significant PC. We perf...
