Abstract The large literature on software reliability assessment and prediction is essentially concerned with parametric models. During the last decade non-parametric models have been developed. This paper presents a new non-parametric model which is based on the idea of separation of concern between the long term trend in reliability growth and the local behaviour The trend is captured using moving averages while the local behaviour is estimated using a kernel estimator. The predictions obtained from the new model are compared with predictions that come from earlier models on some real data sets. A simulation study is also conducted.

两阶段非参数软件可靠性模型

摘要 关于软件可靠性评估和预测的大量文献主要关注参数模型。在过去的十年中，已经开发了非参数模型。本文提出了一种新的非参数模型，该模型基于可靠性增长的长期趋势与局部行为之间的关注点分离思想。趋势是使用移动平均线捕获的，而局部行为是使用核估计器估计的。将从新模型获得的预测与来自早期模型在某些真实数据集上的预测进行比较。还进行了模拟研究。
