[R] Estimate zero inflated mixed model parameter

[xqzhang85 at yahoo.com]

Hi, I can not estimate the zero inflated mixed model parameters successfully. If it is possible, would you please help me write the code? In my case, I consider the location as a random effect. My data are:

location y x1 x2 x3
1    
1
1
2
2
2
3
3
3    

Thank you very much.
Yours,
