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 T 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

a = 1.4224
b = 0.0011
s = 0.0428
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 51.67%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0428) – 1
= 18.69%

Exp(Y643)
= Exp(a + b × X643 + 2 × s)
= Exp(a + b × 937 + 2 × s)
= Exp(1.4224 + 0.0011 × 937 + 2 × 0.0428)
= Exp(2.5774)
= $13.16
Bottom border of price channel:
Exp(Y643)
= Exp(a + b × X643 – 2 × s)
= Exp(a + b × 937 – 2 × s)
= Exp(1.4224 + 0.0011 × 937 – 2 × 0.0428)
= Exp(2.4061)
