factor_agent.evaluator.Evaluator.tried

Evaluator.tried()

The tried trials’ names, in the order they joined, and the matrix of their correlations.

A tried trial is kept as its normal scores on every TRIED_SAMPLE_EVERY-th scored date; the correlation of two is the mean over those dates of the correlation of their normal scores among the day’s members, NaN for a pair without a usable date. Each tried trial holds about 2 MB on 3000 members over 15 years (600 trials, 1.3 GB), and the matrix is its square.
