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
  • weighted_sum
  • mean
  • weighted_mean

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