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 RHI 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
Primary Trend
Start date: July 23, 2021
End date: July 25, 2024
a = 4.8731
b = -0.0004
s = 0.1106
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0004) – 1
= -12.85%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1106) – 1
= 55.64%

Top border of price channel:
Exp(Y502)
= Exp(a + b × X502 + 2 × s)
= Exp(a + b × 728 + 2 × s)
= Exp(4.8731 + -0.0004 × 728 + 2 × 0.1106)
= Exp(4.8201)
= $123.98
Bottom border of price channel:
Exp(Y502)
= Exp(a + b × X502 – 2 × s)
= Exp(a + b × 728 – 2 × s)
= Exp(4.8731 + -0.0004 × 728 – 2 × 0.1106)
= Exp(4.3777)
= $79.66

Top border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(4.8731 + -0.0004 × 1,826 + 2 × 0.1106)
= Exp(4.4065)
= $81.98
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(4.8731 + -0.0004 × 1,826 – 2 × 0.1106)
= Exp(3.9641)
= $52.68
