Rate and rate ratio.
What are they? In human health it is generally the case that the more people studied, and the longer the surveillance of them, the greater the number of new occurrences of any specified condition there are likely to be. This is because of the increase in total time ‘at risk’ of having an event, that is, the increased persons-and-time of observation. A rate is an arithmetic way of quantifying th...
متن کاملOdds Ratio, Hazard Ratio and Relative Risk
Odds ratio (OR) is a statistic commonly encountered in professional or scientific medical literature. Most readers perceive it as relative risk (RR), although most of them do not know why that would be true. But since such perception is mostly correct, there is nothing (or almost nothing) wrong with that. It is nevertheless useful to be reminded now and then what is the relation between the rel...
متن کاملMars/moon Cratering Rate Ratio Estimates
This article presents a method to adapt the lunar production function, i.e. the frequency of impacts with a given size of a formed crater as discussed by Neukum et al. (2001), to Mars. This requires to study the nature of crater-forming projectiles, the impact rate difference, and the scaling laws for the impact crater formation. These old-standing questions are reviewed, and examples for the r...
متن کاملMulti-document summarization using distortion-rate ratio
The current work adapts the optimal tree pruning algorithm(BFOS) introduced by Breiman et al.(1984) and extended by Chou et al.(1989) to the multi-document summarization task. BFOS algorithm is used to eliminate redundancy which is one of the main issues in multi-document summarization. Hierarchical Agglomerative Clustering algorithm(HAC) is employed to detect the redundancy. The tree designed ...
متن کاملBias of using odds ratio estimates in multinomial logistic regressions to estimate relative risk or prevalence ratio and alternatives.
Recent studies have emphasized that there is no justification for using the odds ratio (OR) as an approximation of the relative risk (RR) or prevalence ratio (PR). Erroneous interpretations of the OR as RR or PR must be avoided, as several studies have shown that the OR is not a good approximation for these measures when the outcome is common (> 10%). For multinomial outcomes it is usual to use...
