LMM Parameter Estimates for Polycentricity Interaction Effects

Restricted maximum likelihood parameter estimates and fitting statistics for indicators in linear mixed models. The dataset, shared by Juan Zhu on figshare, focuses on the interaction effect between centers and an index on polycentricity. It is a small 5.5 KB Excel file last updated on June 1, 2026.

Use Cases

• Validate statistical models for polycentric urban development based on the reported parameter estimates.
• Benchmark fitting statistics for linear mixed models in spatial analysis.
• Analyze interaction effects between urban centers and polycentricity indices.
• Reproduce or extend statistical analyses of polycentricity using the provided model outputs.

Strengths

• File size is 5.5 KB, indicating a focused and easily downloadable dataset.
• Data is shared under a permissive CC-BY-4.0 license.
• Includes restricted maximum likelihood estimates, a specific and advanced statistical method.

Limitations

• Row count and column definitions are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The 5.5 KB size suggests a very limited scope, likely containing only summary statistics.
