Abstract

We hope to assess the different processing methodologies or the effectiveness of the devices or systems applied in this nonparametric statistical test by observing the failure behavior of the recorded survival data. The proposed second-order approach of new better than used (NBU 2) will be employed, which requires that the test data behaves either like NBU 2 property or exponentially. If the survival data is NBU 2, the proposed treatment method is likely to be beneficial. If the data are exponential, on the other hand, the recommended treatment method has no positive or negative influence on patients, as shown in the application section. To establish the validity of the test, we calculated the power of the proposed test and efficiency on both complete and censored data, compared the results to those of existing tests, and then applied the test to a range of real-world data.

摘要

我们希望通过观察记录的生存数据的失效行为,评估应用于该非参数统计检验的不同处理方法或设备/系统的有效性。我们将采用拟议的二阶新优于旧(NBU2)方法,该方法要求检验数据表现为 NBU2 特性或指数特性。如果生存数据符合 NBU2,那么所建议的处理方法可能是有益的。另一方面,如果数据呈指数分布,那么所推荐的处理方法对患者没有正面或负面影响,正如应用部分所示。为了验证检验的有效性,我们计算了拟议检验在完整数据和截尾数据上的功效和效率,并将结果与现有检验进行了比较,然后将该检验应用于一系列实际数据。
