qgcomp.cox.boot works on complete case data. For now, error codes will be updated to reflect this, as I'm not sure having this as an invisible error is advisable (though the...

"poisson" has been used numerous times with no apparent issues. If using the bootstrap version of qgcomp, it's advisable to set MCsize to a value greater (say 10x) than the...

Late update: the Cox model version similarly performs well. If using the bootstrap version of qgcomp, it's advisable to set MCsize to a value greater (say 10-50x) than the sample...

Late update: Hurdle and zero inflated model versions similarly performs well. If using the bootstrap version of qgcomp, it's advisable to set MCsize to a value MUCH greater (say 100-1000x)...

Note that a GEE-like approach to clustered data (e.g. longitudinal measurements on individuals) can be done using qgcomp.boot functions with the `id` parameter set to the cluster identifier. Like a...

Note this approach has now been implemented by Welch et al in https://doi.org/10.1016/j.envint.2021.106787

There is also a gist with a brief example of this: https://gist.github.com/alexpkeil1/1887e2f87d92e682c517dd8fe74415b4

Estimating equation methods (e.g. `qgcomp.glm.ee`) have supplanted bootstrap methods when they are available. These methods use a robust variance estimator that is appropriate in scenarios in which GEE might be...
