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 AIR 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: March 12, 2020
End date: June 25, 2021
a = 1.9429
b = 0.0024
s = 0.1563
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0024) – 1
= 144.32%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1563) – 1
= 86.85%

Top border of price channel:
Exp(Y212)
= Exp(a + b × X212 + 2 × s)
= Exp(a + b × 308 + 2 × s)
= Exp(1.9429 + 0.0024 × 308 + 2 × 0.1563)
= Exp(3.0093)
= $20.27
Bottom border of price channel:
Exp(Y212)
= Exp(a + b × X212 – 2 × s)
= Exp(a + b × 308 – 2 × s)
= Exp(1.9429 + 0.0024 × 308 – 2 × 0.1563)
= Exp(2.3842)
= $10.85

Top border of price channel:
Exp(Y537)
= Exp(a + b × X537 + 2 × s)
= Exp(a + b × 778 + 2 × s)
= Exp(1.9429 + 0.0024 × 778 + 2 × 0.1563)
= Exp(4.1596)
= $64.05
Bottom border of price channel:
Exp(Y537)
= Exp(a + b × X537 – 2 × s)
= Exp(a + b × 778 – 2 × s)
= Exp(1.9429 + 0.0024 × 778 – 2 × 0.1563)
= Exp(3.5344)
= $34.28
