Variance

Weight coefficient (accuracy 0.1)

Smoothed data line

Traditional criterion (1/5)

Relatively centered numerical value

a = 0.2, b = 0.2, c = 0.2

Non-smooth, can’t keep peaks well, smoothing faster

Local-midpoint criterion

Relatively small numerical value

a = 0.3, b = 0.2, c = 0.15

Smoother, better noise reduction, smoothing speed in general

Local-mean criterion

Relatively minimum numerical value

a = 0.3, b = 0.2, c = 0.15

Smoother, better noise reduction, smoothing speed in general

Global-mean criterion

Relatively large numerical value

a = 0.4, b = 0.1, c = 0.2

Non-smooth, can retain peaks, and the degree of noise reduction is generally
