Error limit in equivalent circuit analysis

[Krupa]

Dear All,

              What is the maximum acceptable error limit in equivalent circuit analysis?

My rule of thumb is that if the relative standard error of the residuals of the fit, what I call
SsubF, is 10% or greater that is a poor fit; 3-5% probably acceptable and meaningful; and 2% or less good.  Values of 1% or less are excellent.  One must also look at the estimates of the values all the free-to-vary parameters of a fit and if the relative standard error of a given estimate is large, 15% or more, it is poorly determined.  The RMS value of the these errors for all the free parameters should be less than 5% for a meaningful and significant fit.
