WebJun 13, 2016 · To do that, we need to dive into two plots, namely the ACF and PACF—and this is where it gets tricky. Interpreting ACF and PACF Plots. The ACF stands for Autocorrelation function, and the PACF for Partial Autocorrelation function. Looking at these two plots together can help us form an idea of what models to fit. WebIntroduction. This vignette focuses on MCMC diagnostic plots, in particular on diagnosing divergent transitions and on the n_eff and Rhat statistics that help you determine that the chains have mixed well. Plots of parameter estimates from MCMC draws are covered in the separate vignette Plotting MCMC draws, and graphical posterior predictive model …

WebOn this plot the ACF is significant only once (in reality the first entry in the ACF is always significant, since there is no lag in the first entry - it’s the correlation with itself), while the PACF is geometric. Hence it is an MA(1) process. WebThe following plot is a time series plot of the annual number of earthquakes in the world with seismic magnitude over 7.0, ...
