Final fixed parameters estimates
In the Linear Mixed Effects object, the final fixed effects parameter estimates are computed by solving:
T00b = y0
where:
T00 and y0 are elements of the reduced data matrix as defined in the section on “Restricted maximum likelihood”.
are the final fixed parameters estimates.
When there are multiple solutions, a convention is followed such that if any column of T00 is a linear combination of preceding columns, then the corresponding final fixed parameters estimate element is set to zero.
