QFASA Robustness to Assumption Violations: Computer Code

Quantitative fatty acid signature analysis (QFASA; Iverson et al. 2004. Ecological Monographs 74:211-235) has become a common method of estimating diet composition, especially for marine mammals, but the performance of the method has received limited investigation. This software was developed to compare the bias of several QFASA estimators using computer simulation and develop recommendations regarding estimator selection (Bromaghin et al. 2015. Assessing the robustness of quantitative fatty acid signature analysis to assumption violations. Methods in Ecology and Evolution (publication expected in late 2015 or early 2016).定量脂肪酸特征分析（Quantitative Fatty Acid Signature Analysis, QFASA；Iverson等人，2004年，《生态专著》（Ecological Monographs）74卷：211-235页）现已成为估算饮食组成的常用方法，尤其广泛应用于海洋哺乳动物类群，但该方法的性能表现尚未得到充分研究。本软件开发旨在通过计算机模拟对比多款QFASA估计器的偏差，并针对估计器的选择提出针对性建议（Bromaghin等人，2015年。《评估定量脂肪酸特征分析对假设违背的稳健性》，《生态与进化方法》（Methods in Ecology and Evolution），预计2015年末或2016年初刊出）
