1 Fitting kinetic models

Imagine that we are interested to see how the spectrum changes over time during some experiment.

For that, we first need to select time as covariate. We then try to describe by means of kinetic models how the intensity of each spike evolves over time.

For each species/\(m/z\), SPIX

For each species, the ``best’’ kinetic model is selected among a library of 7 models with different shapes:
