Phylogenetic Model Parameter Estimations for Invariable Site Plus Gamma

2020 research data by Lam-Tung Nguyen evaluates parameter estimation for the invariable site plus discrete Gamma model in phylogenetics. The dataset supports analysis of model identifiability and optimization heuristic performance for shape parameter, proportion of invariable sites, and tree length.

Use Cases

• Compare estimated shape parameter and proportion of invariable sites across different optimization heuristics.
• Analyze the correlation between the fraction of invariable sites and fractions of sites with slow evolutionary rates.
• Assess the accuracy of tree length estimations under the invariable site plus discrete Gamma model.
• Validate proposed improved optimization heuristics for estimating model parameters.

Strengths

• Data originates from peer-reviewed research on a widely used phylogenetic model.
• Focuses on the critical and disputed estimation of model parameters like shape and invariable site proportion.
• Associated with a CC0 1.0 public domain license for unrestricted reuse.

Limitations

• Specific data volume, format, and structure (e.g., row/column counts) are not provided in the input.
• The dataset is from 2020 and may not reflect the latest software implementations or methodological debates.
• Scope is limited to the invariable site plus Gamma model, not general phylogenetic data.
