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 BA 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: October 29, 2025
a = 3.4651
b = 0.0011
s = 0.0741
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 50.26%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0741) – 1
= 34.50%

Exp(Y934)
= Exp(a + b × X934 + 2 × s)
= Exp(a + b × 1,359 + 2 × s)
= Exp(3.4651 + 0.0011 × 1,359 + 2 × 0.0741)
= Exp(5.1296)
= $168.94
Bottom border of price channel:
Exp(Y934)
= Exp(a + b × X934 – 2 × s)
