CSS Physical and Inorganic Chemistry P-I QUESTION #1416
Question 1
In chemometrics, multivariate calibration involves:
  • Using multiple independent variables to predict dependent variables✔️
  • Using regression only on X-data
  • Performing correlation without regression
  • None of these
Correct Answer Explanation
Multivariate calibration in chemometrics uses multiple independent variables (e.g., spectral data at multiple wavelengths) simultaneously to build predictive models for dependent variables (e.g., concentration). Techniques like Principal Component Regression (PCR) and Partial Least Squares (PLS) are commonly used. It goes beyond simple univariate regression.
