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 SR 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: November 20, 2024
a = 3.1583
b = 0.0006
s = 0.0272
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 23.22%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0272) – 1
= 11.51%

Top border of price channel:
Exp(Y1,040)
= Exp(a + b × X1,040 + 2 × s)
= Exp(a + b × 1,512 + 2 × s)
= Exp(3.1583 + 0.0006 × 1,512 + 2 × 0.0272)
= Exp(4.0776)
= $59.01
Bottom border of price channel:
Exp(Y1,040)
= Exp(a + b × X1,040 – 2 × s)
= Exp(a + b × 1,512 – 2 × s)
= Exp(3.1583 + 0.0006 × 1,512 – 2 × 0.0272)
= Exp(3.9687)
= $52.92

= Exp(4.2573)
= $70.62
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
