❝ :lol3: I’m always a little bit skeptic when one tries to validate own code (including f**ing expensive “validation packs” sold by vendors of commercial software). Hence, we have to find another one. Cross-validation would do.

I may be able to validate wagner-nelson in ivivc for R (assumes 1-comp model) with numerical deconvolution/convolution using RIVIVC package (no asumption about model structure) but there isn't enough hours in the day. will do at some stage.

suggestion: the ivivc for R can be updated to do numerical deconvolution/convolution option because what if the disposition is not 1 comp, then wanger-nelson is limited.
