plot()
forcheck_overdispersion()
@bwiernik and @mccarthy-m-g - I think the implementation works quite well now for the first methods. The plot()
method works fine for the Q-Q plots (https://github.com/easystats/see/pull/329). Things we should consider:
-
We would have to update the plot for overdispersion/zero-inflation checks (see https://github.com/easystats/performance/pull/643#issuecomment-1999544659). This is still based on the classical residuals, not the simulated ones. I have played around with revising the current code, copying the function
.diag_overdispersion
into a new.new_diag_overdispersion
(see https://github.com/easystats/performance/blob/ad60db15550c406e533ad037107c81d81a66590d/R/check_model_diagnostics.R#L296). This did not really work - do you have any ideas how we can have new plots for overdispersion/zero-inflation? I found these plots quite informative and would like to keep them, beside the Q-Q plot. See also discussion here. -
check_zeroinflation()
andcheck_overdispersion()
now rely onsimulate_residuals()
for zero-inflated or negative binomial models etc., so only the really "simple" models that returned identical results to DHARMa-tests still use the old code. Only Poisson mixed models also use the "old" code, which still could be inaccurate (see #464) - do we want to usesimulate_residuals()
in general for mixed models when callingcheck_zeroinflation()
andcheck_overdispersion()
? -
How do we want to deal with y axis limits when
detrend = TRUE
in Q-Q plots? (see https://github.com/easystats/performance/pull/643#issuecomment-1999548863) -
A method for
check_autocorrelation()
is not yet implemented. Since the DHARMa tests require additional information, I'm not sure about how to best implement such methods.
