Automated Spectral Data Normalization and Outlier Detection

spectroscopy data normalization VBA outlier detection
Prompt
Design an advanced Excel VBA macro that performs multi-stage spectral data normalization for scientific instrument readings. The macro must: 1) Automatically detect and handle outliers using modified Z-score method, 2) Apply multi-point calibration correction, 3) Generate comprehensive statistical summary with confidence intervals, 4) Create interactive heat map visualization of normalized data. Include error handling for different spectroscopic data formats from UV-Vis, FTIR, and mass spectrometry instruments.
