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 POR 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 = 2.3621
b = 0.0008
s = 0.0249
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 36.18%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0249) – 1
= 10.48%

Top border of price channel:
Exp(Y1,042)
= Exp(a + b × X1,042 + 2 × s)
= Exp(a + b × 1,517 + 2 × s)
= Exp(2.3621 + 0.0008 × 1,517 + 2 × 0.0249)
= Exp(3.6953)
= $40.26
Bottom border of price channel:
Exp(Y1,042)
= Exp(a + b × X1,042 – 2 × s)
= Exp(a + b × 1,517 – 2 × s)
= Exp(2.3621 + 0.0008 × 1,517 – 2 × 0.0249)
= Exp(3.5957)
= $36.44

Top border of price channel:
Exp(Y1,243)
= Exp(a + b × X1,243 + 2 × s)
= Exp(a + b × 1,806 + 2 × s)
= Exp(2.3621 + 0.0008 × 1,806 + 2 × 0.0249)
= Exp(3.9398)
= $51.41
Bottom border of price channel:
Exp(Y1,243)
= Exp(a + b × X1,243 – 2 × s)
= Exp(a + b × 1,806 – 2 × s)
