29 Results: The most accurate ActiGraph wrist cut-points (Kim, vector magnitude: ≤ 3958 30 counts/60s and vertical axis: ≤ 1756 counts/60s) demonstrated good classification accuracy 31 (ROC-AUC = 0.85-0.86) and accurately estimated SB time in 5-8y (equivalence p=0.02; 32 mean bias: ...
Cut points are used to indicate the separation characteristics of solids control equipment at a given moment in time. The performance of the equipment, in addition to the condition of the drilling fluid, should be taken into consideration in the assessment of cut point data. Cut point curves ...
在DolphinDB中,cutPoints是用于将连续变量离散化的函数。离散化是将连续变量划分为若干个离散的区间,可以帮助我们更好地理解和分析数据。 cutPoints函数的语法如下: cutPoints(column, numBins) 参数说明: column: 需要离散化的列名或向量。 numBins: 离散化后的区间个数。
Accelerometer cut-points for absolute and relative intensities were defined using ROC-curve analyses.The ROC-curve analyses for accelerometer cut-points revealed good-to-excellent accuracy (AUC >0.8), defining cut-points for absolute intensity (2, 3, 4, 5, 6, 7 METs for PP and 2 to 6 ...
A method is described for choosing optimal cut-points in screening test with a continuous score in order to divide people into any number of disease categories. The cut-points are chosen to minimize the overall expected loss, given a matrix of losses incurred by misclassifications. It is shown...
0.9–1 excellent while 1.0 indicates a perfect test. The optimal cut-point is the closest to the upper left corner of the ROC-curve figure, representing 100% sensitivity and 100% specificity. To identify the most appropriate sensitivity and specificity value as the cut-points, we used the dis...
