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 SEE 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: October 20, 2021
End date: May 3, 2024
a = 4.8020
b = -0.0008
s = 0.0879
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0008) – 1
= -26.58%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0879) – 1
= 42.15%

Top border of price channel:
Exp(Y481)
= Exp(a + b × X481 + 2 × s)
= Exp(a + b × 699 + 2 × s)
= Exp(4.8020 + -0.0008 × 699 + 2 × 0.0879)
= Exp(4.3862)
= $80.33
Bottom border of price channel:
Exp(Y481)
= Exp(a + b × X481 – 2 × s)
= Exp(a + b × 699 – 2 × s)
= Exp(4.8020 + -0.0008 × 699 – 2 × 0.0879)
= Exp(4.0345)
= $56.51

Top border of price channel:
Exp(Y1,118)
= Exp(a + b × X1,118 + 2 × s)
= Exp(a + b × 1,625 + 2 × s)
= Exp(4.8020 + -0.0008 × 1,625 + 2 × 0.0879)
= Exp(3.6024)
= $36.69
Bottom border of price channel:
Exp(Y1,118)
= Exp(a + b × X1,118 – 2 × s)
= Exp(a + b × 1,625 – 2 × s)
= Exp(4.8020 + -0.0008 × 1,625 – 2 × 0.0879)
= Exp(3.2507)
= $25.81
