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 NOC 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: February 28, 2022
End date: July 9, 2025
a = 6.0406
b = 0.0001
s = 0.0590
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 2.94%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0590) – 1
= 26.64%

Top border of price channel:
Exp(Y285)
= Exp(a + b × X285 + 2 × s)
= Exp(a + b × 413 + 2 × s)
= Exp(6.0406 + 0.0001 × 413 + 2 × 0.0590)
= Exp(6.1915)
= $488.55
Bottom border of price channel:
Exp(Y285)
= Exp(a + b × X285 – 2 × s)
= Exp(a + b × 413 – 2 × s)
= Exp(6.0406 + 0.0001 × 413 – 2 × 0.0590)
= Exp(5.9553)
= $385.80

Top border of price channel:
Exp(Y1,127)
= Exp(a + b × X1,127 + 2 × s)
= Exp(a + b × 1,640 + 2 × s)
= Exp(6.0406 + 0.0001 × 1,640 + 2 × 0.0590)
= Exp(6.2888)
= $538.49
Bottom border of price channel:
Exp(Y1,127)
= Exp(a + b × X1,127 – 2 × s)
= Exp(a + b × 1,640 – 2 × s)
= Exp(6.0406 + 0.0001 × 1,640 – 2 × 0.0590)
= Exp(6.0526)
