Flag bootstrapping argument to be changed to allow parameter uncertainty #329
Description
As a brief follow up and documenting of ideas at meeting 2026-01-27, we noted that:
Paramters.bootstrapAllisfalseby default- This needs enabled for multiruns to bootstrap for parameter uncertainty
- The user may not know that this is the case (missing from documentation)
Possible small changes to better handle this:
- Add in bootstrapping to wiki
- Parameter
bootstrapAllcould be de-finalised and made modifiable in config file and CLI args (via multirun class) - For multiruns the parameter could be set to
true(and left as-is for GUI runs) - OR, could set a warning flag in console in multiruns to alert the user that no bootstrapping is ideal for development environment but this should be enabled for valid statistical outputs
A few possible changes which can easily be made. Can discuss ongoing!

@matteorichiardi @dav-sonn This is the issue that was just discussed in today's meeting regarding bootstrapping - it is still listed as in progress on the SimPaths development board, so I didn't think opening a new issue seemed appropriate.
The current state of the code is that
bootstrapAllis alwaystrue, in other words bootstrapping is always on, even for single runs. I don't know if this was intended or not, but from today's discussion I gather it's likely not.I recall that we previously discussed a few possible solutions in a development meeting, including:
The latter might be the most straightforward - e.g. by adding a static method
Parameters.setBootstrapAllanalogous to the existingParameters.setTrainingFlag, which can be called inSimPathsStartandSimPathsMultiRunto set different values (thefinalkeyword would need to be removed from thebootstrapAlldeclaration).andrewbaxter439 commentedon Oct 27, 2026
A suggested approach implemented in #549
