When you create an analytic model, you: • Define data cubes, dimensions, cube collections, and other parts that are used to organize and calculate individual fields of data. • Map records to cube collections within the analytic model. • Map individual record fields to data cubes and ...
The results of the evaluation are depicted in Fig. 3. Fig. 3 Results of PSNR, SSIM and NMSE from both test data sets DatawoA and DatawA (calculated using virtual and real 3D subtraction angiographies; box plot: yellow line : median; box : IQR = Q3-Q1; whiskers_low = Q1...
Alternate names: Median, quartile, decile, percentile, etc (which are all specific examples of quantiles) Summary: This is an improved version of the calculation describedhere. Quantiles divide ordered data into a series of essentially equal-sized data subsets; the quantiles are the data values ma...

importance of standard error standard errors produce simplistic measures of uncertainty in a value. they are often used because, in many cases, if the standard error of some individual quantities is known, then we can easily calculate the standard error of some function of the quantities. also,...
Denote by HRk(t) (k=1,2) the cause-specific hazard ratios, that is, the hazard ratios of the individual components, and by HR∗(t) the all-cause hazard ratio of the composite endpoint T^{(g)}_{*}. Define the geometric average hazard ratio, gAHR, as the exponentiated mean of th...
Price Index Level (Alternative Calculation Formula – Contribution Method) Another way to calculate the index level would be to use the initial weight and price return of the individual securities included in the index: PriceIndexLevelUSDt PriceIndexLevelUSDt-1 * (1 SecurityPr ice...
For improving the quality of the solutions, four effective neighborhood operators are introduced. In the local search, a rule is given to save the operation time and a problem-based search operator is proposed to improve the quality of the best individual. Finally, a ...

We provide a sample size calculation method for a composite endpoint (CE) based on the geometric average hazard ratio (gAHR) in case the proportional hazards assumption can be assumed to hold for the components, but not for the CE. Methods: The required number of events, sample size and ...
