Free hazard ratio calculator: calculate HR, confidence intervals & p-values for hazard ratios. ➤ How to interpret hazard ratios for time to event data / survival curves. Difference between hazard ratio and relative risk.
and hHI refer to hazard ratio logarithms based on functional relationships between mortality and the Z scores of the respective anthropometric measures height, body mass index, a body shape index, and hip index. ARI is the sum of these 4 quantities. The metabolic syndrome score MS score is the...
ratio is 17:1, which is worse than that of the district. the student population is made up of 48% female students and 52% male students. the school enrolls 71% economically disadvantaged students. there are 46 equivalent full-time teachers. at a glance student/teacher ratio 17:1 math ...
Afterwards, with the help of the “Raster Calculator,” the twelve factors were cumulated to obtain the FPI [47] in two scenarios: (I) with the weights computed as explained in the Methodology or (II) with equal weights (8.33%). Table 2 contains the comparison matrix. Based on the com...
In this study, the Raster Calculator function of QGIS software was used to calculate the normalized-difference vegetation index (NDVI) value of each period of images. Then, the NDVI image-subtraction method was used to find the critical difference in NDVI before and after each weather event. Sp...
can contribute to our ability to predict and manage floods. Various methods are commonly used to map flood sensitivity. Recent methods such as multicriteria evaluation, decision tree analysis (DT), fuzzy theory, weight of samples (WoE), artificial neural networks (ANN), frequency ratio (FR) and...
It is calculated as the ratio between the number of true predictions and the total number of samples in the dataset. Cross-Validation (CV) Cross-validation is a resampling method used to test the predictive robustness of a statistical model [73,74]. The idea is to further split the ...
Floods are a widespread natural disaster that occur in most areas of the world, except for the polar regions. To minimize the damage caused by floods, effective management strategies and policies must be implemented. Petra and Wadi Musa areas are prone t
For this purpose, we use the Stochastic Event Set Calculator tool from the Openquake Engine [39,48]. The generated catalog must be long enough to estimate correctly the hazard for the return period of interest, 5000 years (equivalent to a probability of exceedance of 1.0% in 50 years). ...
