### Arguments

| Argument                            | Description                                                                                                                          |
| ----------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| `column`                            | Column on which to compute the window variance. Must be numeric.                                                                     |
| `window size / static window start` | Size of rolling window calculation. If two window values are provided, this is the 1st row number for the static window calculation. |
| `static window end`                 | Optional, default is `None`. 2nd row number for static window calculation.                                                           |
