estimate of biased error for overdetermined calibration with
multiple connections of each standard
- takes:
- std_names: list of strings to uniquely identify each
- standard.*
- returns:
- systematic error: mwavepy.Network type who’s .s_mag is
- proportional to the systematic error metric
- note:
- mathematically, this is
- mean_s(|mean_c(r)|)
- where:
- r: complex residual errors
mean_c: complex mean taken accross connection
mean_s: complex mean taken accross standard
