Numerical errors from ODE solvers can mess up optimisation and inference very easily

(Subtitle: “when you’ve got a lot of data points!”) This post is for people interested in doing optimisation or inference with Differential Equation (DE) models. If you are a statistician, you might be used to treating model simulators as black … Continue reading

Initial conditions and steady states

Today I came across a good (or bad, depending on how you look at it) example of initial conditions / steady-states having a massive effect on model behaviour. I think it is generally a good idea to get a model … Continue reading
