效果大小Effect Size(例如Cohen的d或h):计算实验中观察到的效果大小的标准化方法;确切的统计数据取决于正在比较的内容和所使用的假设检验:对于两种均值之间的差异,经常使用Cohen的 d,而Cohen的 h 是专门为两种比例之间的差异。 样本大小Sample Size(n):研究或实验中使用的观察值或人数。 显著性水平Significance Level...
Current recommendations for assessing power and sample size in mediation models include using a Monte Carlo power analysis simulation and testing the indirect effect with a bootstrapped confidence interval. Unfortunately, these methods have rarely been adopted by researchers due to limited software options...
Determining optimal power down of a system while indexes are being rebuilt A method, system and computer-readable medium for managing the building of indexes are presented. In one embodiment, the method includes the steps of: initiating an index rebuilding process in a computer; detecting a "...

None of them justified the sample size. However, such sample sizes do not allow for normality testing, thus, graphical approaches should be used. Parametric approaches result in higher statistical power when compared to their non-parametric counterparts. Repeated measures analysis should always be ...
Full size image Synthetic zircon age distributions calculated (Methods) from the thermal model output illustrating the effect of under-sampling on the modeled zircon spectra are shown in Fig. 5 for a system assembled with a magma flux of 9.1 × 10−6 km3 km−2 yr−1 over 1.5...
Factors for Determining Ampacity of Conductors 来自 EBSCO 喜欢 0 阅读量: 33 作者: Stallcup, James 摘要: Explains technical aspects to determine the amp capacity of conductors in electric engineering layouts. Measurement of temperature variants; Determination of the size of the ampacity of a ...
Full size image Model bias effect occurred in 2D projection matching was reported by Bronwyn et al.15for ribosomes inM. pneumoniaecells, where the resolution was unrealistically high. We performed SNR-weighted projection matching on their dataset (EMPIAR-10731)15with 50S ribosomes segmented from the...
Full size table Moderation hypotheses analysis To test hypotheses H6–H10, we used Hayes’s (2013) moderation process program for SPSS to examine the moderation effects of students’ internship motivation on the interaction between college students’ EA and EI; between college students’ SN and EI...
Since the model is position invariant, meaning that the model is able to correctly mark the area of different image parts regardless of where in the image they appear, we can apply it for the analysis of new error cases. 3.6. Extracting a Fixed-Size Feature Vector from Instance Segmentation...
