Plot Residual#
Fit an affine function and plot the residual.
import numpy as np
import hyperspy.api as hs
Create a signal:
data = np.arange(1000, dtype=np.int64).reshape((10, 100))
s = hs.signals.Signal1D(data)
Add noise:
s.add_poissonian_noise(random_state=0)
Create model:
m = s.create_model()
line = hs.model.components1D.Expression("a * x + b", name="Affine")
m.append(line)
Fit for all navigation positions:
