PRESENCE code

[Tanvi Gurjar]

Hello everyone, 

I realize that this is a off-topic inquiry, however, I do not have a better way of addressing this and am therefore, posting this here. Apologies in advance. 

I was hoping to get access to the code that was implemented in the paper on multi-state occupancy (https://www.jstor.org/stable/27651247) by Nichols et al. (2007). Since my emails to the authors have gone unanswered so far, I was wondeing if anyone here might be able to help me out with this. 

Many thanks and best regards, 

Tanvi
