How-to guides

Task-focused recipes. Each guide assumes you know the basics — see the Tutorials first.

Guide	Task
Manual peak setup	Build PeakSpec objects explicitly, set bounds and mix kinetic models
Robust fitting and loss functions	Choose the right RobustOptions for your noise model
Uncertainty budget	Configure UncertaintyOptions and interpret uc_curve
Fix and freeze parameters	Use PeakSpec.fixed to hold parameters constant during fitting
Synthetic curves with noise	Generate reference data with Poisson noise and fit with matching weights
Automatic initialization	Use autoinit_multi for exploratory analysis on unfamiliar datasets
Serialize and archive results	Export and reload MultiFitResult as JSON
