R help - May 2018 - Tackling of convergence issues in gamlss vs glm2

Hello:

I'd like to know how and if the GLM convergence problems are addressed in
gamlss.
For simplicity, let's focus on Normal and Negative Binomial with log link.
The convergence issues of the glm() function were alleviated in 2011 when glm2
package was released.
Package gamlss was released in 2012, so it might still use the glm-like solution
or call glm() directly.
Is that the case or the improvements from glm2 have been incorporated into
gamlss also?

Regards,
Nik

If you do not receive a satisfactory reply to this rather technical
question -- this list is *mainly* about R programming -- you might try
directly emailing the maintainer: ?maintainer. This assumes of course that
you have thoroughly read package documentation + checked any of its listed
references (which I have obviously not).

You might also check the package code, though this often leads to C code
resources, which is kinda tough.

Cheers,
Bert
