Explanations

These are developer-focused explanations of internal pylcm mechanisms. They are designed for contributors and advanced users who want to understand how pylcm works under the hood.

• Function Representation — What the function representation does and how it works.

• Interpolation and Extrapolation — How pylcm’s coordinate finders and map_coordinates handle interpolation and extrapolation across grid types.

• Approximating Continuous Shocks — Quadrature rules and Markov chain approximations for IID and AR(1) shock processes.

• Stochastic Transitions — Why regime, discrete state, and continuous shock transitions use different runtime representations.

• Dispatchers — How productmap, vmap_1d, and simulation_spacemap evaluate scalar functions on structured spaces.
