Invariant

A/C (PTA-p*p/ISA-i*i)

\(\Delta {\tilde{\mathbf{w}}}^{{\left( {{\text{A}}/{\text{C}}} \right)}} = {\hat{\boldsymbol{\beta }}}\Delta {\mathbf{w}}^{{\left( {{\text{A}}/{\text{C}}} \right)}}\)

Yes

B/D (ITA-p*p/PSA-i*i)

\(\Delta {\tilde{\mathbf{w}}}^{{\left( {{\text{B}}/{\text{D}}} \right)}} = \hat{{\boldsymbol{\beta }}}{\bf W}\left( {{\hat{\mathbf{q}}\mathbf{V}}^{ - 1} {\hat{\mathbf{g}}} - {\mathbf{U}}} \right)\Delta {\mathbf{d}} \ne \hat{\boldsymbol{\beta }}\Delta {\mathbf{w}}^{{\left( {{\text{B}}/{\text{D}}} \right)}}\)
