Sensitivity matrices—relative difference (in \(\%\)) between each coefficient of the derived models \({\mathrm {SM}}_{\mathrm {v}}\), \({\mathrm {SM}}_{\mathrm {vNS}}\), \({\mathrm {SM}}_{\mathrm {vEW}}\), \({\mathrm {SM}}_{\mathrm {vNSEW}}\), \({\mathrm {SM}}_{{\Gamma ^{(1)}}}\), \({\mathrm {SM}}_{{\Gamma ^{(1)}}\delta }\) and MF7 (a–f) resp. CM5 (g–l) in a degree versus order matrix
