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 DLB 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 = 4.1227
b = 0.0002
s = 0.0605
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 8.86%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0605) – 1
= 27.37%

Top border of price channel:
Exp(Y322)
= Exp(a + b × X322 + 2 × s)
= Exp(a + b × 466 + 2 × s)
= Exp(4.1227 + 0.0002 × 466 + 2 × 0.0605)
= Exp(4.3520)
= $77.64
Bottom border of price channel:
Exp(Y322)
= Exp(a + b × X322 – 2 × s)
= Exp(a + b × 466 – 2 × s)
= Exp(4.1227 + 0.0002 × 466 – 2 × 0.0605)
= Exp(4.1101)
= $60.95

= Exp(4.5469)
= $94.34
Bottom border of price channel:
Exp(Y898)
= Exp(a + b × X898 – 2 × s)
= Exp(a + b × 1,304 – 2 × s)
