[R-sig-ME] Advice

[Julie Webbs]

Dear lme4 Authors


My model  is:  persons are crossed with an item  and nested with job
interviewers. P Χ (Items: interviewers)


I would like to compute var. Com.  using lme4 ( with all random effects) ,
but I do not know how to write codes using lme4, specially when factors are
nested.


The matrix is :


p     interviewers    item

1         1                 10

1          2                11

2          1                 13

2          2                 14

.           .                   .

.           .                   .


I really appreciate for your advise, Looking forward to hearing from you


Many thanks

Julie
