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 LII 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: September 16, 2024
End date: December 4, 2025
a = 7.0836
b = -0.0005
s = 0.0598
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -15.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0598) – 1
= 27.04%

Top border of price channel:
Exp(Y948)
= Exp(a + b × X948 + 2 × s)
= Exp(a + b × 1,379 + 2 × s)
= Exp(7.0836 + -0.0005 × 1,379 + 2 × 0.0598)
= Exp(6.5759)
= $717.62
Bottom border of price channel:
Exp(Y948)
= Exp(a + b × X948 – 2 × s)
= Exp(a + b × 1,379 – 2 × s)
= Exp(7.0836 + -0.0005 × 1,379 – 2 × 0.0598)
= Exp(6.3366)
= $564.88

= Exp(7.0836 + -0.0005 × 1,823 + 2 × 0.0598)
= Exp(6.3739)
= $586.36
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(7.0836 + -0.0005 × 1,823 – 2 × 0.0598)
= Exp(6.1346)
