May 17, 2023 · I am familiar with computing the autocorrelation function of a time series as a function of time lag, but I am not sure what it means for a time series to itself be autocorrelated.

Nov 11, 2020 · Additionally, 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.

You 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 …

Nov 21, 2013 · Can somebody explain autocorrelation function in a time series data? Applying acf to the data, what would be the application?

Nov 11, 2015 · very easy to follow and helpful for a first timer like me to test for autocorrelation. I have found autocorrelation occuring in some of my linear regression models, but I haven't got such a …

So 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 …

Apr 10, 2013 · I was wondering what does it mean when time series residuals have autocorrelation? How should I deal with it?

Apr 19, 2023 · With the command rotation="estimated", it does indeed appear that the spatial autocorrelation is corrected! The only problem that remains, however, is that when I use my real …

Jul 7, 2020 · I 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 …

Feb 21, 2019 · I have noticed signs of temporal autocorrelation between count and variable "d" (which are individual years for a time-series dataset). Despite reading Kasper Kristensen's vignette, I'm still …
