GLMMADMB PACKAGE PDF

Description Usage Arguments Details Value Note References See Also Examples Description Fits extended generalized linear mixed-effects models to data using a variety of distributions and link functions, including zero-inflated models. Random effects terms should be enclosed in parentheses x g , where x represents the formula for the parameter s that vary across grouping variables and g represents the grouping variables; for example, 1 g indicates a model where only intercepts vary across groups. Grouping variables must be factors. The model may include an offset term, which must be specified on the scale of the linear predictor and included in data: see offset. Alternatively, the random effects terms may be specified separately using the random argument.

Its capabilities include: a wide range of families response distributions , including non-exponential families such as negative binomial type 1 and 2 , Beta, logistic, and truncated Poisson and negative binomial distributions as well as the standard exponential families binomial, Poisson, Gamma, Gaussian. Go to the Buildbot page and retrieve a binary that is compatible with your OS. In general, the file name format is something like glmmadmb-r[version]-[OS]-[compiler]-[nbit]bit.

In general you want to look for the highest numbered version compatible with your system go to the bottom of the list and scroll up, except that the Windows versions are named differently and ended up at the top of the list. For example, as of today 7 Oct I would choose from among the following: glmmadmb-mingwrwindows8-mingw Try your code again and see if that helped. If you encounter this problem, your choices are: Upgrade your system to a more recent version of MacOS if possible.

Build glmmadmb from its TPL file on your machine. This will be a bit tricky if you are not reasonably experienced. Download the full AD Model Builder source code from the AD Model Builder download page and follow the directions for building AD Model Builder from source; you may need to install Xcode, and you may need to ask for help at users admb-project. Googling "admb macos We recommend the R mixed models list at r-sig-mixed-models r-project.

For now, the resulting package is slower than the old single-random-effect version , but we hope to increase its speed in the future. In order to use glmmADMB effectively you should already be reasonably familiar with generalized linear mixed models GLMMs , which in turn requires familiarity with i generalized linear models e. In order to fit a model in glmmADMB you need to: specify a model for the fixed effects, in the standard R Wilkinson-Rogers formula notation see? Formulae can also include offsets. For example, the formula would be 1 block for a random-intercept model or time block for a model with random variation in slopes through time across groups specified by block. Random effects can be specified either in a separate random argument as in nlme or as part of the model formula as in lme4. In the current version, zero-inflation can only be specified as a single constant term across the entire model — i.
