Area of Science:

  • Analytical Chemistry
  • Chemometrics

Background:

  • Multivariate calibration is essential for analyzing complex chemical data.
  • Key factors influencing model reliability are frequently underestimated in practice.

Purpose of the Study:

  • To present the fundamental principles of multivariate calibration.
  • To highlight critical, often neglected, considerations for developing robust calibration models.

Main Methods:

  • Discussion of sampling design strategies.
  • Analysis of the impact of predictor noise on model performance.
  • Evaluation of parameter significance for model assessment.

Main Results:

  • Sampling design significantly affects regression model reliability.
