Description
We can probably improve the fit (avoid overfitting) by applying a multivariate model, rather than each income group independently.
As one example, OG-USA applies a multivariate KDE for modeling bequests.

Research direction
Start by locating the current capital-gains distribution model and how it treats income groups independently. Read the linked OG-USA multivariate KDE documentation for comparison, then determine how a joint model would be evaluated for fit and overfitting. Done means the distribution is modeled across income groups together with evidence that the fit improves without overfitting.
