[R-sig-ME] glmmADMB package
Automatic Differentiation Model Builder. Click here to edit contents of this page. Some complex variance structures heterogeneous yes, AR1 no. Does anyone have any suggestions about a function or package that I could use to get this? Uses sparse matrices and Average Information for speed.
Complex and custom variance structures possible. Multiple denominator degrees of freedom methods Kenward Roger, Satterthwaite, Containment. Unless otherwise stated, the content of this page is licensed under Gllmmadmb Commons Attribution-ShareAlike 3.
variance – Calculate R2 for a GLMM using glmmADMB – Cross Validated
Under active development, especially for GLMMs. Bayesian priors can be included. Widely used in plant and animal breeding. I have run a full set of models for my ecological data set and have selected my best model based on AICc.
Numerous error structures supported. Email Required, but never shown.
na.action within glmmADMB package?
No complex variance structures. Home Padkage Tags Users Unanswered. I have tried the following functions: Constraints on parameters allowed. Started out as a commercial product, but now open-source. Append content without editing the whole page source. Ported from S-plus to R.
Something does not work as expected? Much faster than nlme. Kirsten Reid 11 3.
However it becomes quadratically slow as the number of observations increases because of the need to do two eigenvalue decompositions of order nearly equal to the number of observations. Now that I have my best model, I want to obtain an R2 value for this model. So it is a good choice when fitting large numbers of small data sets, but not a good choice for fitting large data sets.
