Requests an RMS (square root of the sum of the squares) multiparameter sensitivity [4, p. 204] calculation for the circuit elements named on the .SENSA or .SENSR record. The RMS multiparameter sensitivity is defined as the square root of the sum of the squared magnitudes of the individual complex element sensitivities. A .SENSA or a .SENSR record must also be included in the analysis. If a .SENSA record is included, the multiparameter sensitivity is the RMS value of the appropriate absolute element sensitivities. If a .SENSR record is included, the multiparameter sensitivity is the RMS value of the appropriate relative element sensitivities.
