Description

My understanding of v1.1 on CRAN is that only 1 performance metrics is implemented for regression (mean absolute error?) and classification (overall accuracy?). It would be great to implement more metrics like:

Numeric outcomes

  • R-squared
  • mean absolute error

Binary outcomes

  • AUC
  • PRAUC
  • F1
  • sensitivity
  • specificity
  • PPV
  • NPV
  • Matthew's correlation coefficient

3+ category outcomes

  • "one-vs-all" versions of all of the binary metrics, as well as the average across classes

Research direction

Start by locating the existing regression and classification performance-metric entry points in the v1.1 implementation. Review how the current metric is exposed and tested, then determine how the requested numeric, binary, and one-vs-all multiclass metrics should fit that structure. Done means the listed metrics are implemented with coverage for multiclass averages.
