CumProd / Computation Layer

Calculate the running product of values in a column. Similar to pandas cumprod() or running product in SQL.

For each position i: $y_{i} = j = 1 \prod i x_{j}$

Applications:

Compound growth calculations
Sequential multipliers
Factorial computations

Note: Ignores null values. May require attention to overflow for large sequences.
