Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of GM price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e

End date: March 26, 2025
a = 2.6382
b = 0.0008
s = 0.1031
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 32.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1031) – 1
= 51.04%

Top border of price channel:
Exp(Y691)
= Exp(a + b × X691 + 2 × s)
= Exp(a + b × 1,002 + 2 × s)
= Exp(2.6382 + 0.0008 × 1,002 + 2 × 0.1031)
= Exp(3.6134)
= $37.09
Bottom border of price channel:
Exp(Y691)
= Exp(a + b × X691 – 2 × s)
= Exp(a + b × 1,002 – 2 × s)
= Exp(2.6382 + 0.0008 × 1,002 – 2 × 0.1031)
= Exp(3.2010)
= $24.56

= Exp(a + b × 1,745 + 2 × s)
= Exp(2.6382 + 0.0008 × 1,745 + 2 × 0.1031)
= Exp(4.1836)
= $65.60
Bottom border of price channel:
Exp(Y1,201)
= Exp(a + b × X1,201 – 2 × s)
= Exp(a + b × 1,745 – 2 × s)
= Exp(2.6382 + 0.0008 × 1,745 – 2 × 0.1031)
