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 BJRI 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: March 7, 2022
End date: March 31, 2025
a = 3.0252
b = 0.0003
s = 0.1018
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 12.15%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1018) – 1
= 50.27%

Top border of price channel:
Exp(Y486)
= Exp(a + b × X486 + 2 × s)
= Exp(a + b × 705 + 2 × s)
= Exp(3.0252 + 0.0003 × 705 + 2 × 0.1018)
= Exp(3.4503)
= $31.51
Bottom border of price channel:
Exp(Y486)
= Exp(a + b × X486 – 2 × s)
= Exp(a + b × 705 – 2 × s)
= Exp(3.0252 + 0.0003 × 705 – 2 × 0.1018)
= Exp(3.0430)
= $20.97

= Exp(3.8021)
= $44.79
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(3.0252 + 0.0003 × 1,825 – 2 × 0.1018)
= Exp(3.3948)
