Re: RRM in ASReml

Dear Tomasz,

The ASReml tutorial session C4 discusses random regression.
You can find it on the VSN website at http://www.vsni.co.uk/software/asreml/user-area/tutorials/

One way of doing it based on your example would be for a data file with the fields
  cow dim milk

BNasic Random Regression
 Cow * # Assumes coded 1 to n as in your example
 DIM # covariate -
 milk
Milk.dat
 milk ~ mu DIM DIM.DIM !r !{ Cow Cow.DIM Cow.DIM.DIM !}
0 0 1
Cow
3 0 US !GP
.1 .01 .1 .01 .01 .1
Cow

Now there are many variations on this theme possible
such as using leg(DIM,2).Cow i.e.

milk ~ mu DIM DIM.DIM !r leg(DIM,2).Cow
0 0 1
leg(DIM,2).Cow 2
3 0 US !GP
.1 .01 .1 .01 .01 .1
Cow
