Modules

black_litterman

The approximate backtest's Black-Litterman: the posterior per bar ahead of the mean-variance kernels.

covariance

The approximate backtest's batched covariance estimates: every decision bar's at once, in low-rank form.

mean_variance

The approximate backtest's mean-variance: every decision bar's Markowitz weights in compiled code.

top_n

The approximate backtest's top-n: every decision bar's equal-weight book at once.

topk_dropout

The approximate backtest's TopkDropout: the decision bars solved forward, the book drifting between them.
