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: August 6, 2021
End date: May 6, 2024
a = 4.5642
b = -0.0007
s = 0.1008
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.92%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1008) – 1
= 49.68%

Top border of price channel:
Exp(Y340)
= Exp(a + b × X340 + 2 × s)
= Exp(a + b × 492 + 2 × s)
= Exp(4.5642 + -0.0007 × 492 + 2 × 0.1008)
= Exp(4.3973)
= $81.23
Bottom border of price channel:
Exp(Y340)
= Exp(a + b × X340 – 2 × s)
= Exp(a + b × 492 – 2 × s)
= Exp(4.5642 + -0.0007 × 492 – 2 × 0.1008)
= Exp(3.9940)
= $54.27

Top border of price channel:
Exp(Y1,030)
= Exp(a + b × X1,030 + 2 × s)
= Exp(a + b × 1,496 + 2 × s)
= Exp(4.5642 + -0.0007 × 1,496 + 2 × 0.1008)
= Exp(3.6452)
= $38.29
Bottom border of price channel:
Exp(Y1,030)
= Exp(a + b × X1,030 – 2 × s)
= Exp(a + b × 1,496 – 2 × s)
= Exp(4.5642 + -0.0007 × 1,496 – 2 × 0.1008)
= Exp(3.2419)
= $25.58
