Hi everyone, I’m currently working on validating the posterior distribution of a SEIRS model using the az.plot_ppc function from the ArviZ library. However, when I generate the posterior predictive checks, the plot only shows a single straight line, which is not what I expected.(Everything else wor…

I found the solution with my friend’ s help. See this post: [image] Lotka-Volterra with manual gradients by Sanmitra Ghosh Mathematical models are used ubiquitously in a variety of science and engineering domains to model the time evolution of physical variables. These mathematical model…
