Request NLMIXED codes to help ZINB in two correlated datasets

youliqing — Thu, 30 Dec 2021 05:07:12 GMT

Greetings all,

I request examples and NLMIXED codes to help ZINB (Zero-Inflated Negative Binomial) outcomes in two correlated datasets: 1) 215 persons clustered in 42 neighorhoods and 2) 238 mothers assessed at three waves in a longitudinal randomized controlled trial.

I tried these codes below and contacted authors with related publications which I found in PubMed. I could not find good examples to help me write NLMIXED codes for two correlated datasets.

Thank you. Sincerely! Happy Holidays!
Qing

Robin High wrote several excellent papers about analyzing count data by using PROC NLMIXED. He has many examples, including ZINB models.
