as.families("BEINF") not working about gamboostlss HOT 5 CLOSED

OK, all those families have FAM()$type == "Mixed", found that in my own code.

Apparently I had already implemented such cases for 3-parametric families and was only too lazy to do the same also for the 4-paremetric ones. Should be fixed now in "devel".

Thanks for finding this! This should be a problem for all inflated families, e.g. BEOI():

BEINF()$nopar
[1] 4
 BEOI()$nopar
[1] 3

But their corresponding functions for the derivatives BEOI()$dldm have arguments mu and sigma only which leads to the error.

I think we should be able to fix this in our code, I'll take a look.

Thanks a lot!

Perhaps there are even more families with similar properties?
Could check this issue by comparing nopar with the number of parameters in dldm either by simply calling the functions or by computing on

deparse(gamlss.dist::as.gamlss.family("BEINF")$dldm)[1]

for all available families in a loop?

Merci :)
