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: November 4, 2024
a = 4.7728
b = -0.0006
s = 0.1081
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -19.65%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1081) – 1
= 54.11%

Top border of price channel:
Exp(Y162)
= Exp(a + b × X162 + 2 × s)
= Exp(a + b × 236 + 2 × s)
= Exp(4.7728 + -0.0006 × 236 + 2 × 0.1081)
= Exp(4.8477)
= $127.44
Bottom border of price channel:
Exp(Y162)
= Exp(a + b × X162 – 2 × s)
= Exp(a + b × 236 – 2 × s)
= Exp(4.7728 + -0.0006 × 236 – 2 × 0.1081)
= Exp(4.4152)
= $82.70

Top border of price channel:
Exp(Y1,120)
= Exp(a + b × X1,120 + 2 × s)
= Exp(a + b × 1,627 + 2 × s)
= Exp(4.7728 + -0.0006 × 1,627 + 2 × 0.1081)
= Exp(4.0141)
= $55.38
Bottom border of price channel:
Exp(Y1,120)
= Exp(a + b × X1,120 – 2 × s)
= Exp(a + b × 1,627 – 2 × s)
= Exp(4.7728 + -0.0006 × 1,627 – 2 × 0.1081)
= Exp(3.5817)
