Model selection and inference for time series

Placeholder. How to select models when you can’t simply cross-validate away your pain.

Rob Hyndman explains how to cross-validate time series models that use only the lagged observations. Cosma Shalizi mentions the sample splitting problem for time series for post-selection inference and has supervised students to do some work with it, notably Robert Lunde.
