Bayesian Cost Effectiveness Analysis. Given the results of a Bayesian model (possibly based on MCMC) in the form of simulations from the posterior distributions of suitable variables of costs and clinical benefits for two or more interventions, produces a health economic evaluation. Compares one of the interventions (the "reference") to the others ("comparators"). Produces many summary and plots to analyse the results

Inconsistency in summary table #44

Closed giabaio closed 1 year ago

giabaio commented 1 year ago

@n8thangreen I think there's a slight inconsistency in the way you've refactored the summary method. You have coded rownames(EU_tab) <- he$interventions[c(he$ref, he$comp)] which implies that the first row of the table must be the reference intervention. But this doesn't propagate to the full table, so in the examples I was checking, you actually have data in the order provided by the eff, cost matrices (so: first column=intervention1, second column=intervention2 and so, with no reference to the choice of the reference intervention), but then the row names are not matching that.

The drawback is that you'd get blatant inconsistencies, such as with the most cost-effective intervention not being associated with the highest expected utility (simply because of reordering of the row labels...).

I've fixed it temporarily by simply changing the code above to rownames(EU_tab) <- he$interventions --- but I'm not sure this breaks something else down the line...

Can you please when you have a moment have a look?

Thanks!

Hi @giabaio I'm not quite sure what to do. Could you send me a reprex, please? what is the example you're looking at? whats the error and what should it be? Thanks!
