    Thank you very much for the explanation. Any chance that you can share a link that may explain the interpretation of interactions in a NB or ZINB models?

    Thank you so much for your videos!! I have a brief question, in the case of negative binomial in panel data, would you recommend using this library glmmTMB? thank you a lot in advance for your answer :)

    Hi Dr. Kebbe, I'm a PhD candidate currently working on my dissertation research. My response variable follows a zero-inflated beta distribution. Would you have any advice for me to model this? I am having trouble finding an R package that allows me to do that.

    What keyboard do you use? Or is it just the keyboard on your macbook?

    I was just wondering if something like this was actually necessary for my data. Turns out it lowered the AIC by 155.

    It's , really interesting
    I'm going to put ZIP for bioChemists data set, if is it possible please make mode on that data set.
    Thank you

    I want to know how to interpret the data after we get over the result of a zero-inflated negative binomial. How to define the coefficient-and-variable in a data relationship

    I am using negative binomial zero inflated mixed model for my thesis project on gut microbiome in babies. I have 48 subject measured at three different points. The subjects are from 2 different locations. They are evaluated for allergy at later stage..so how i find the right model

      Hi Sanuja, thank you for watching. This will depend entirely on what research question you are hoping to answer, how your data looks like, etc... You may consider the glmm.zinb package that allows for random effects to account for a longitudinal design, if this fits with your purposes.

      I want to find how a genus varies over different time points in subjects from both locations. Will the model be
      zinb = (counts = Time + location|Subject + offset (log(N)), link ="logit", dist = "negbin", data = data4)
      where counts = count data of bacterial taxa
      N - total no of reads in each sample
      Time - week 1, week 4, week 24
      location - X and Y.
      And after running this model, what is the next step? do i use the predict function? Sorry I am new to this topic
      Thanks
