Move to statistical cleaning.
Given steps taken above, it should be programmatically impossible to get impossible HDDS values, so this could also be removed.

Suggest to include the IPC calculations in a dedicated script.
That script would require the execution of the upstream scripts that calculate indicators (HDDS, Share of food expenditures,...)
