Data from: Joined at the hip: linked characters and the problem of missing data in studies of disparity
- 负责人：
- DOI：

- 摘要：
- Paleontological investigations into morphological diversity, or disparity, are often confronted with large amounts of missing data. We illustrate
Data from: Incomplete specimens in geometric morphometric analyses

- 摘要：
- ny of these methods are intolerant of missing data, which can limit the use of rare taxa and hinder the study of broad patterns of ecological diversi
Data from: Biases with the Generalized Euclidean Distance in disparity analyses with high levels of missing data

- 摘要：
- ing morphospace, but a detailed study of this possible effect was still lacking. Here, we test if the percentage of missing data for a taxon artificially influences
Data from: Testing of the effect of missing data estimation and distribution in morphometric multivariate data analyses
- 负责人：
- DOI：
- doi:10.5061/dryad.m01st7p0
- 摘要：
- Missing data are an unavoidable problem in biological datasets and the performance of missing data deletion and estimation techniques
Data from: Bias and sensitivity in the placement of fossil taxa resulting from interpretations of missing data
- 负责人：
- DOI：
- doi:10.5061/dryad.7tq20
- 摘要：
- missing data make this problematic. The complex taphonomic processes occurring during fossilization can make it difficult to distinguish absence from

Data from: Unforeseen consequences of excluding missing data from next-generation sequences: simulation study of RAD sequences
- 负责人：
- DOI：
- doi:10.5061/dryad.jf361
- 摘要：
- e studies excluding loci with missing data, while others include them, even when sequences are missing from a large number of individuals. Here we use
Data from: A hierarchical Bayesian approach for handling missing classification data
- 负责人：
- DOI：
- doi:10.5061/dryad.8h36t01
- 摘要：
- . When individuals are observed but not classified, these “partial” observations must be modified to include the missing data mechanism to avoid spurious inference

- 摘要：
- molecular sequence data. For many datasets, the computational challenge lies in the huge dimension of the missing data. Here, we introduce an importa
