Description

It will make it easier to use LensKit effectively if we automate support for standard or widely-accepted inferences:

  • pairwise t-tests (with and without correction)
  • confidence intervals on model performance
  • effect sizes and associated confidence intervals

Supporting Bayesian inference will be a separate ticket.

Research direction

The issue names no files, tests, or entry points. First locate the existing model-performance evaluation APIs and tests, then scope support for pairwise t-tests, corrected and uncorrected comparisons, confidence intervals, and effect sizes with associated intervals; Bayesian inference is explicitly out of scope.
