Maybe you weren't looking at the documentation? On page 12 of the GLLAMM manual (http://biostats.bepress.com/cgi/viewcontent.cgi?article=1160&context=ucbbiostat), the authors explicitly list each of the links and families (as well information for ordered categorical data). On that page, the authors list "complimentary log-log" as one of the link functions. Maybe you should first try explaining your data and what inference you hope to make/models you would like to fit and see if anyone has other suggestions for fitting a model that would be easier to defend and/or interpret.
HTH,
Billy

(it is hard to tell as there is no list of the available links for each family anywhere and the writer of the command does not respond to emails.) -gllamm- offers the family(poisson) distribution but no loglog link. does anyone know if there is there is a way to recreate survival analysis log-log results using a -gllamm- regression?
