Parameters

Ynnp.array(2d)

The design matrix after inserting the new run at position pos

Zslist(np.array(1d) or None)

The grouping matrices of the old design (before insertion)

posint

The position of the inserted run

colstartnp.array(1d)

The starting column of each factor

Returns

anp.array(1d)

For each factor, the group that run belongs to
