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 PH 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: May 6, 2022
End date: February 28, 2025
a = 4.8005
b = 0.0011
s = 0.0624
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 49.34%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0624) – 1
= 28.33%

Top border of price channel:
Exp(Y401)
= Exp(a + b × X401 + 2 × s)
= Exp(a + b × 581 + 2 × s)
= Exp(4.8005 + 0.0011 × 581 + 2 × 0.0624)
= Exp(5.5637)
= $260.79
Bottom border of price channel:
Exp(Y401)
= Exp(a + b × X401 – 2 × s)
= Exp(a + b × 581 – 2 × s)
= Exp(4.8005 + 0.0011 × 581 – 2 × 0.0624)
= Exp(5.3142)
= $203.21

Top border of price channel:
Exp(Y1,106)
= Exp(a + b × X1,106 + 2 × s)
= Exp(a + b × 1,610 + 2 × s)
= Exp(4.8005 + 0.0011 × 1,610 + 2 × 0.0624)
= Exp(6.6944)
= $807.90
Bottom border of price channel:
Exp(Y1,106)
= Exp(a + b × X1,106 – 2 × s)
= Exp(a + b × 1,610 – 2 × s)
= Exp(4.8005 + 0.0011 × 1,610 – 2 × 0.0624)
= Exp(6.4450)
