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

Start date: December 3, 2021
End date: April 19, 2024
a = 4.0363
b = -0.0002
s = 0.0539
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -6.77%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0539) – 1
= 24.05%

Top border of price channel:
Exp(Y594)
= Exp(a + b × X594 + 2 × s)
= Exp(a + b × 858 + 2 × s)
= Exp(4.0363 + -0.0002 × 858 + 2 × 0.0539)
= Exp(3.9792)
= $53.48
Bottom border of price channel:
Exp(Y594)
= Exp(a + b × X594 – 2 × s)
= Exp(a + b × 858 – 2 × s)
= Exp(4.0363 + -0.0002 × 858 – 2 × 0.0539)
= Exp(3.7637)
= $43.11

= Exp(3.8124)
= $45.26
Bottom border of price channel:
Exp(Y1,190)
= Exp(a + b × X1,190 – 2 × s)
= Exp(a + b × 1,726 – 2 × s)
