A more robust biologically based ranking criterion for treatment plans.

چکیده
which has been adopted by several authors (2–4), has some undesirable properties. For example, changing the absolute value of the NTCP in two competing treatments plans by the same proportion can sometimes change the relative ranking of the plans. Langer et al. (1) point out that this is because, if Eq. 1 is used as the score for ranking plans, for a given value of TCP, a small fractional change in NTCP (i.e., dNTCP/NTCP) is reflected in the fractional change in the score as

Ranking of Iran Provinces Based on Changes in Major Labor Force Indicators in the Period 2015-2019, Using the TOPSIS Method
Increase of employment and reduction of unemployment are the most important indicators for community development. Statistical indicators derived from the implementation of the Labor Force Survey design are useful in evaluating employment policies and performances. But, it should also emphasize that using an indicator (such as the unemployment rate) alone cannot be a suitable criterion for asses...
متن کاملCREDIBILITY THEORY ORIENTED PREFERENCE INDEX FOR RANKING FUZZY NUMBERS
This paper suggests a novel approach for ranking the most applicable fuzzy numbers, i.e. $LR$-fuzzy numbers. Applying the $alpha$-optimistic values of a fuzzy number, a preference criterion is proposed for ranking fuzzy numbers using the Credibility index. The main properties of the proposed preference criterion are also studied. Moreover, the proposed method is applied for ranking fuzz...
متن کاملA Bootstrap Interval Robust Data Envelopment Analysis for Estimate Efficiency and Ranking Hospitals
Data envelopment analysis (DEA) is one of non-parametric methods for evaluating efficiency of each unit. Limited resources in healthcare economy is the main reason in measuring efficiency of hospitals. In this study, a bootstrap interval data envelopment analysis (BIRDEA) is proposed for measuring the efficiency of hospitals affiliated with the Hamedan University of Medical Sciences. The propos...
متن کاملFuzzy Robust Regression Analysis with Fuzzy Response Variable and Fuzzy Parameters Based on the Ranking of Fuzzy Sets
Robust regression is an appropriate alternative for ordinal regression when outliers exist in a given data set. If we have fuzzy observations, using ordinal regression methods can't model them; In this case, using fuzzy regression is a good method. When observations are fuzzy and there are outliers in the data sets, using robust fuzzy regression methods are appropriate alternatives....
متن کاملPrediction by Categorical Features: Generalization Properties and Application to Feature Ranking
We describe and analyze a new approach for feature ranking in the presence of categorical features with a large number of possible values. It is shown that popular ranking criteria, such as the Gini index and the misclassification error, can be interpreted as the training error of a predictor that is deduced from the training set. It is then argued that using the generalization error is a more ...
