摘要

在法医笔迹分析中,了解与特定作者相关的调查结果的相对频率至关重要,尤其是在使用统计方法时。在确定不同作者假设的可能性时,会将这些因素考虑在内。然而,如果对比材料中包含了临时写作,那么对比作者习惯的代表性可能会被扭曲。将特别系列的比对写作样本视为内部同质的集合体,每个系列只用一个值来计算比对作家特定发现的平均相对频率,就可以避免某些创作时间点的过度代表性。此外,所提议的方法所产生的发现计数在很大程度上与手写样本的长度无关,这对专家评估的效率和成本效益具有积极影响。

Handling finding counts in handwriting analysis - Avoiding the overrepresentation of unusual writing scenarios.

In forensic handwriting analysis, it is crucial to understand the relative frequencies of findings relevant to the specific author, especially when using statistical methods. These are factored into the likelihoods used to determine the probabilities for the different authorship hypotheses. However, if ad hoc writings are included in the comparison materials, the representation of a comparison writer's habits can be distorted. An overrepresentation of certain creation time points can be avoided by treating ad hoc series of comparison writing samples as internally homogeneous agglomerates, incorporating only a single value per series into the average relative frequency of a given finding for a comparison writer. Additionally, the proposed approach produces finding counts largely independent of the length of the handwriting sample, which has a positive impact on the efficiency and cost-effectiveness of the expert evaluation.
