Spatial autocorrelation can be modelled for withWed, 01 Apr 2026 17:07:00 GMThttps://stats.stackexchange.com/questions/14914/how-to-test-the-autocorrelation-of-the-residualsYou don't need to test for autocorrelation. It is there. The plot shows that. You could look at the autocorrelation function of these residuals (function acf()), but this will simply confirm what can be seen by plain eye: the correlations between lagged residuals are very high.Wed, 01 Apr 2026 19:44:00 GMThttps://stats.stackexchange.com/questions/613457/spatial-autocorrelation-correction-with-glmmtmbThe help info says you can have residual spatial autocorrelation even if the model takes care of it. I added the command rotation="estimated" during the recalculation and the autocorrelation is no longer statistically significant.Fri, 03 Apr 2026 01:20:00 GMThttps://stats.stackexchange.com/questions/167737/autocorrelation-vs-non-stationaryWhat is the relationship between autocorrelation and non-stationary? Is it true that non-zero autocorrelation $\\implies$ non-stationary, but not vice versa?Fri, 03 Apr 2026 07:39:00 GMThttps://stats.stackexchange.com/questions/475950/autocorrelation-in-linear-mixed-models-lmeI disagree that autocorrelation and random intercept are redundant. The random intercept would be a difference in mean for that group (e.g., whale) compared to the whole population, which could be present with or without serial autocorrelation within that group.Wed, 01 Apr 2026 19:37:00 GMThttps://stats.stackexchange.com/questions/55658/how-to-interpret-autocorrelation-of-residuals-and-what-to-do-with-itI was wondering what does it mean when time series residuals have autocorrelation? How should I deal with it?Fri, 03 Apr 2026 12:32:00 GMThttps://stats.stackexchange.com/questions/49265/whats-the-deal-with-autocorrelationSo why is autocorrelation a bad (or good) thing? 2.) The solution I've heard for dealing with autocorrelation is to diff the time series. Without trying to read the author's mind, why would one not do a diff if non-negligible autocorrelation exists? 3.) What limitations do non-negligible autocorrelations place on a model?Thu, 02 Apr 2026 10:18:00 GMThttps://stats.stackexchange.com/questions/475806/how-to-deal-with-autocorrelation-in-mixed-modelsI tried first to apply a linear mixed model (lme) and I had a problem of autocorrelation and non-normality of residuals. Next, I tried to apply a GLM with Poisson and negative binomial distributions. Both had the same problem of autocorrelation and/or non-normality of residuals. What can I do to model these variables or to correct these issues?Wed, 01 Apr 2026 18:26:00 GMThttps://stats.stackexchange.com/questions/496034/whats-the-difference-between-multicollinearity-and-autocorrelationAdditionally, if I made a model and I wanna validate the conditions necessary for it to be a good model, should I test both conditions (multicollinearity and autocorrelation)? or only one of those.Sat, 04 Apr 2026 12:24:00 GMT
