Extend arithmetic operator support for accumulators

Open HDembinski opened this issue 3 years ago • 0 comments

All accumulators support addition and scaling (multiplication by a constant). Additionally, we could support subtraction, multiplication, and division.

Subtraction

  • [ ] count
  • [ ] sum
  • [ ] weighted_sum
  • [ ] mean
  • [ ] weighted_mean

Multiplication

  • [ ] count
  • [ ] sum
  • [ ] weighted_sum
  • [ ] mean
  • [ ] weighted_mean

Division

  • [ ] count
  • [ ] sum
  • [x] weighted_sum
  • [ ] mean
  • [ ] weighted_mean

How to implement division and multiplication for weighted mean is mathematically not clear to me.
