Dear Juan,

Thanks for your patience. This error was caused by a change in another software package list depends on, and we have now resolved the problem. I will send you a test version of the package off-list, and we will release an update to CRAN including the fix soon.

Best,
Graeme

Hi!

Working with my data to verify ceiling and floor liars, I used your replication code as a guide and got error messages about the Log likelihood not being monotonically increasing. But then I realized that I also get this error with your own code on your data, that is simply running the replication of your paper.

In particular when trying to replicate Table 7, columns 3-6, as below, I get the error messages shown below (if I change the fit.start parameter, the error that pops out may change from object not found to non non monotonically increasing Log likelihood, but I always get an error anyways).

In short, before concluding there is problem with my data specifically, given this finding I would like to point it out and make sure there is not a more general problem with the code (perhaps something got messed up in an software update or that of package dependencies?).

Thank you very much,
