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: November 2, 2021
End date: May 2, 2024
a = 4.9344
b = -0.0009
s = 0.0856
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -27.08%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0856) – 1
= 40.80%

Top border of price channel:
Exp(Y573)
= Exp(a + b × X573 + 2 × s)
= Exp(a + b × 830 + 2 × s)
= Exp(4.9344 + -0.0009 × 830 + 2 × 0.0856)
= Exp(4.3874)
= $80.43
Bottom border of price channel:
Exp(Y573)
= Exp(a + b × X573 – 2 × s)
= Exp(a + b × 830 – 2 × s)
= Exp(4.9344 + -0.0009 × 830 – 2 × 0.0856)
= Exp(4.0452)
= $57.12

Top border of price channel:
Exp(Y1,200)
= Exp(a + b × X1,200 + 2 × s)
= Exp(a + b × 1,742 + 2 × s)
= Exp(4.9344 + -0.0009 × 1,742 + 2 × 0.0856)
= Exp(3.5984)
= $36.54
Bottom border of price channel:
Exp(Y1,200)
= Exp(a + b × X1,200 – 2 × s)
= Exp(a + b × 1,742 – 2 × s)
= Exp(4.9344 + -0.0009 × 1,742 – 2 × 0.0856)
= Exp(3.2562)
= $25.95
