Simulated NIR Spectra and Hardness Values for Chemometric Model Calibration

Simulated spectra and hardness values form the core of this 83.0 MB dataset, published on figshare by Mauricio Garrido. The data supports a methodology for determining the sample size required to calibrate reliable near-infrared chemometric models. It was last updated on April 13, 2026.

Use Cases

• Benchmarking sample size determination methods for NIR calibration (inferred from domain, verify after download)
• Developing and testing regression models for predicting material hardness from spectral data (inferred from domain, verify after download)
• Studying the relationship between simulated spectral features and target property accuracy (inferred from domain, verify after download)

Strengths

• Published on figshare under the permissive CC-BY-4.0 license.
• Dataset size is 83.0 MB, indicating a substantial volume of simulated data.
• Last update timestamp is precisely recorded as 2026-04-13 13:47:54.

Limitations

• Metadata is minimal; actual content requires verification after download.
• Row count and column definitions are unknown, which may limit suitability assessment.
• Data consists of simulated spectra, which may not fully capture the complexity of real-world samples.
