simpeg.data.SyntheticData.relative_error#
- property SyntheticData.relative_error#
Relative error of the data.
This can be set using an array of the same size as the data (e.g. if you want to assign a different relative error to each datum) or as a scalar if you would like to assign a the same relative error to all data.
The standard_deviation is constructed as follows:
np.sqrt( (relative_error * np.abs(dobs))**2 + noise_floor**2 )
For example, if you set
>>> data = Data(survey, dobs=dobs) >>> data.relative_error = 0.05
then the contribution to the standard_deviation is equal to
>>> data.relative_error * np.abs(data.dobs)
