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 AEE 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 = 2.9013
b = 0.0010
s = 0.0352
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 42.75%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0352) – 1
= 15.11%

Top border of price channel:
Exp(Y886)
= Exp(a + b × X886 + 2 × s)
= Exp(a + b × 1,284 + 2 × s)
= Exp(2.9013 + 0.0010 × 1,284 + 2 × 0.0352)
= Exp(4.2238)
= $68.29
Bottom border of price channel:
Exp(Y886)
= Exp(a + b × X886 – 2 × s)
= Exp(a + b × 1,284 – 2 × s)
= Exp(2.9013 + 0.0010 × 1,284 – 2 × 0.0352)
= Exp(4.0831)
= $59.33
