%description
Tools for Conditional Regime Analog Forecasting with Trajectories. The
package builds lag and lead trajectory embeddings, detects regimes with
singular value decomposition and changepoint analysis, estimates
transition probabilities between regimes, samples future-trajectory
analogues, and fits smooth empirical forecast distributions. Random-search
hyperparameter tuning ranks candidate models using internal backtests.
