run

Import in python using from mcutils.scripts.non_central_chi.variance import run

mcutils.scripts.non_central_chi.variance.run(data, ncoils=1, epsilon=1e-08)

Estimates the true noise level of the non-central chi distribution

Parameters

• data – (…, N) dataset with N identical volumes (except for noise)

• ncoils – number of coils used in the reconstruction

• epsilon – target precision in the variance estimate

Returns

(…, ) array with the true signal & standard deviation
