1. 分析使用可用数据和仅存在数据的问题是等价的，本文使用这种等价性作为探索推进分析方法的机会的平台。2. 我们建议在可用分析方面取得一些潜在的方法上的进步，这些进步可以通过仅存在文献中的经验教训来实现，例如，使用现代方法来提高预测性能。我们还考虑了由可用方法所激发的仅存在分析的反向潜在进展。3. 尽管在方法论上有这些潜在的进步，也许更大的机会是推进我们对如何将给定方法应用于特定数据集的思考。4. 示例表明，通过以不同的方式应用给定的分析方法，可以对单个数据集获得截然不同的结果——因此，选择了一种分析方法后，研究如何应用它的下一步对性能至关重要。5. 我们回顾了在决定如何应用分析方法时要考虑的一些关键问题：以反映研究设计的方式应用该方法；考虑数据属性；并使用诊断工具来评估给定的分析对手头数据的合理性。
1. The problems of analysing used-available data and presence-only data are equivalent, and this paper uses this equivalence as a platform for exploring opportunities for advancing analysis methodology. 2. We suggest some potential methodological advances in used-available analysis, made possible via lessons learnt in the presence-only literature, for example, using modern methods to improve predictive performance. We also consider the converse - potential advances in presence-only analysis inspired by used-available methodology. 3. Notwithstanding these potential advances in methodology, perhaps a greater opportunity is in advancing our thinking about how to apply a given method to a particular data set. 4. It is shown by example that strikingly different results can be achieved for a single data set by applying a given method of analysis in different ways - hence having chosen a method of analysis, the next step of working out how to apply it is critical to performance. 5. We review some key issues to consider in deciding how to apply an analysis method: apply the method in a manner that reflects the study design; consider data properties; and use diagnostic tools to assess how reasonable a given analysis is for the data at hand.
