A design object is a list of the design matrix (X),
infomation list (info) and parameter list (param) where
X is the design matrix
and
info is a list whose length is the number of effects.
info[[i]] contains the following:
ename name of effect[i]
order order of effect[i]: 0, 1, ..., maxorder
elevels # of levels of effect[i]
df degrees of freedom of effect[i]
erange range of effect[i] in the (full rank) estimable functions
range=cbind(from,to) where
from is the starting independent colmn of effect[i] in X
to is the ending independent column of effect[i] in X
rangef=cbind(from,to) where
from is the starting colmn of effect[i] in X
to is the ending column of effect[i] in X
menum vector of main effect number involved in effect[i]
contained vector of effect numbers which contains effect[i]
where effect number is defined according to the order of column of X.
contains vector of effects which effect[i] contais.
param is a list consisting of
type, drop, maxorder, sort, pattern
Information of estimable function may be added to this object later.
Estimable function in general form is the rows of
matSwp( t(X)%*%X ) %*% t(X)%*%X
Note that all-zero rows are included
A design object with the following list attached to it:
ef=list(type, Q, ef, locnz)
where Q is the EF in numeric form
and ef is the EF in SAS format.
