Obviously, the rows of T 1 are not linearly independent. Therefore, (7.12) does not have a unique solution in for given p, if T 1 is used instead of T. In such a case, some authors still call a parameter, though unidentifiable. In this book, only identifiable parameters are called parameters.

It is clear that the row spaces of the matrices T and T 1 are the same, so if denotes the parameter in the representation based on Table 7.8, then for each , there should be a , such that

which is possible if T′ has an inverse. In that case,
