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 NARI 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: January 13, 2021
End date: May 7, 2024
a = 4.7686
b = -0.0006
s = 0.1121
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -19.46%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1121) – 1
= 56.57%

Top border of price channel:
Exp(Y162)
= Exp(a + b × X162 + 2 × s)
= Exp(a + b × 236 + 2 × s)
= Exp(4.7686 + -0.0006 × 236 + 2 × 0.1121)
= Exp(4.8528)
= $128.10
Bottom border of price channel:
Exp(Y162)
= Exp(a + b × X162 – 2 × s)
= Exp(a + b × 236 – 2 × s)
= Exp(4.7686 + -0.0006 × 236 – 2 × 0.1121)
= Exp(4.4045)
= $81.82

Exp(Y995)
= Exp(a + b × X995 + 2 × s)
= Exp(a + b × 1,446 + 2 × s)
= Exp(4.7686 + -0.0006 × 1,446 + 2 × 0.1121)
= Exp(4.1355)
= $62.52
Bottom border of price channel:
Exp(Y995)
= Exp(a + b × X995 – 2 × s)
= Exp(a + b × 1,446 – 2 × s)
= Exp(4.7686 + -0.0006 × 1,446 – 2 × 0.1121)
= Exp(3.6871)
= $39.93
