Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T.

| Reproducibility Variable | Result | LLM Response |
|---|---|---|
| Research Type | Experimental | Moreover, empirical results suggest that the log-convexity assumption cannot be relaxed completely: Figure 1 provides an example where the LS-EM algorithm may converge to 0 (an undesired solution) with constant probability when the log-concavity property is violated. See Appendix H for additional numerical results. |
