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 APPF 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: April 26, 2022
End date: July 25, 2024
a = 3.2851
b = 0.0013
s = 0.0815
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0013) – 1
= 62.87%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0815) – 1
= 38.56%

Top border of price channel:
Exp(Y611)
= Exp(a + b × X611 + 2 × s)
= Exp(a + b × 888 + 2 × s)
= Exp(3.2851 + 0.0013 × 888 + 2 × 0.0815)
= Exp(4.6349)
= $103.01
Bottom border of price channel:
Exp(Y611)
= Exp(a + b × X611 – 2 × s)
= Exp(a + b × 888 – 2 × s)
= Exp(3.2851 + 0.0013 × 888 – 2 × 0.0815)
= Exp(4.3087)
= $74.34

Exp(Y1,175)
= Exp(a + b × X1,175 + 2 × s)
= Exp(a + b × 1,709 + 2 × s)
= Exp(3.2851 + 0.0013 × 1,709 + 2 × 0.0815)
= Exp(5.7320)
= $308.59
Bottom border of price channel:
Exp(Y1,175)
= Exp(a + b × X1,175 – 2 × s)
= Exp(a + b × 1,709 – 2 × s)
= Exp(3.2851 + 0.0013 × 1,709 – 2 × 0.0815)
= Exp(5.4058)
