sole trader, partnership, shareholder and rental losses counted as profits

The SIAL income table counts takes abs() of sole trader, partnership, shareholder and rental net profits. This means losses are counted as profits.

Furthermore, there are some values of suspiciously large magnitude (e.g. greater than 100 million). As no individual is likely to have profits or losses that are so large within a single year a filter should be applied to automatically sanitize such extreme values.

Just some background around the reason for not filtering, when the SIAL was first built the team decided not to do any filtering as our transformations may not always align with what other people want to do (in this case what should the cut off be set to and what if people disagree with it?). It was decided that the users would decide what sort of filtering and transformations they would like to apply.

Thanks for that perspective Ernestynne. In that case we probably want a note or a warning some where that no filtering is undertaken OR that filtering is required/recommended.
