Some complex variance structures heterogeneous yes, AR1 no. Welcome page What is a Wiki Site? WikiPlan tools for participatory design of cities. Ported from S-plus to R. Sign up using Facebook. Numerous error structures supported. Find out what you can do. Edit History Tags Source.

Multiple functions lme for linear, nlme for nonlinear, gls for no random terms. Complex and custom variance structures possible. Something does not work as expected? Sign up or log in Sign up using Google.
Under active development, especially for GLMMs. F statistics sans denominator df: Does anyone have any suggestions about a function or package that I could use to get this?
P This function tends to be fast and reliable, compared to competitor functions which fit randomized block models, when then number of observations is small, say no more than PQL only, warnings in documentation. Automatic Differentiation Model Builder. No complex variance structures. Nested random effects easily modeled. Constraints on parameters allowed.
Started out as a commercial product, but now open-source. Click here to hlmmadmb contents of this page. Click here glmmadmv toggle editing of individual sections of the page if possible. Now that I have my best model, I want to obtain an R2 value for this model. It also has other features such as simpler syntax to request predictable functions of random effects. So it is a good choice when fitting large numbers of small data sets, but not a good choice for fitting large data sets.
Bayesian priors can be included. However it becomes quadratically slow as the number of observations increases because of the need to do two eigenvalue decompositions gkmmadmb order nearly equal to the number of observations. Kirsten Reid 11 3.
