Misfit

The difference between two datasets.

Misfit analysis is used in controlled-source electromagnetic modelling studies. Different resistive bodies are added to a background model to represent competing hypotheses that may explain the target zone. The simulated electromagnetic response for each hypothesis can then be compared with the measured data. The misfit plot shows how well the datasets agree.

Misfit analysis is also an important as a quality control measure for inversion, as it shows how well the inverted resistivity model explains the measured data.
