Abstract :
We present a new joint model with random effects for the correlated
count with extra zero and continuous responses. In this model, we
assume a Zero-Inflated Beta-Binomial distribution for the analysis of overdispersed
binomial variable and a normal distribution for the analysis of continuous
response. Furthermore, a full model likelihood function approach is
used to obtain maximum likelihood estimates of the model parameters. We
also evaluate the proposed model using the Monte Carlo simulation method.
Finally, we fit the model to real data to find effective factors on mixed responses.
