Extract individual slopes
Extracts the individual slopes (alpha_i) from a feis object created by
feis.

further arguments. |
The function extracts a matrix containing the individual slope parameters (alpha_i),
which equals the coefficient(s) of regressing the depenent variable on the slope parameter(s).
If slope variables are perfectly collinear within a cluster, one variable is dropped
and the function returns 0 for the respective slope and cluster.
An N x J matrix containing the individual slopes for each cluster unit N
and slope variable J. Rownames indicate the cluster id.
