This tutorial discusses the growth curve of dugongs animals using statistical modeling techniques. The tutorial starts by estimating a frequentist linear model using log-transformed age as the predictor and length of animals as the response variable. The model provides a good fit to the data and its prediction performance is evaluated using a leave-one-out method. Then, the same model is estimated using a Bayesian approach with flat priors on the parameters. The Bayesian approach yields similar results to the frequentist approach but allows for incorporating prior knowledge and uncertainty. Finally, a non-linear model is used to estimate the growth curve using a Bayesian approach, providing more flexibility in modeling the growth trajectory. The tutorial provides a practical introduction to statistical modeling techniques, emphasizing the importance of model selection and evaluation.
