#AVSED PREDCTIONS ASREML HOW TO#

as.asrtests Forms an asrtests. Multiway tables are specified by forming an interaction type term from the classifying variables, that is, separating the variable names with the : operator. predictions, along with those statistics, associated with the predictions and their pairwise differnces, that have been supplied. classify: A character string giving the variables that define the margins of the multiway table to be predicted. What needs to be done beyond the point of looking up the coefficients? asreml.obj: asreml object for a fitted model.

Predicted values and standard errors are returned in the predictions component of the asreml object. ASReml provides a stable platform for delivering well established procedures while also deliv-ering current research in the application of linear mixed models. The predict.asreml method passes the list of user specifications for the prediction design matrix to the REML routines through the predict argument of asreml.

If yes, why is predict() partially refitting the asreml model, which may take several minutes for ~8000 observations (where a complete fit took ~30 minutes). Prediction equations are formed just prior to the final iteration in asreml.

, with the argument tables specifying which tables are printed. Tables are produced using predictPlus.asreml, in conjunction with.

Are BLUEs the coefficients/effects of the mixed effects model in all cases, if no, what is the difference? This function forms the predictions for each term in terms using a supplied asreml object and predictPlus.asreml.

This confuses me, and leads to my three questions: Even though the result is exactly the same as I get when just reading the coefficients from the data structure of the model using coef, which completes virtually instantaneously. The second approach, predict, itself calls update.asreml which leads to some iterative algorithm, it seems to partially refit the model even though it was already fitted to the data before.

predict() (calls asreml:::predict.asreml()) like in this forum post.

coef() (calls asreml:::coef.asreml()) like in this SO answer or in this blog entry.

#AVSED PREDCTIONS ASREML HOW TO#

I am using asreml-R to model genotypic effects of crop field trials and I am confused on how to get best linear unbiased estimates for crop varieties of the model.
