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 NOV 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: July 31, 2023
End date: March 31, 2025

a = 3.7025

b = -0.0006

s = 0.0526

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -18.31%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0526) – 1
= 23.41%

Top border of price channel:

Exp(Y837)
= Exp(a + b × X837 + 2 × s)
= Exp(a + b × 1,216 + 2 × s)
= Exp(3.7025 + -0.0006 × 1,216 + 2 × 0.0526)
= Exp(3.1340)
= $22.97

Bottom border of price channel:

Exp(Y837)
= Exp(a + b × X837 – 2 × s)
= Exp(a + b × 1,216 – 2 × s)
= Exp(3.7025 + -0.0006 × 1,216 – 2 × 0.0526)
= Exp(2.9237)
= $18.61

= Exp(3.7025 + -0.0006 × 1,825 + 2 × 0.0526)
= Exp(2.7967)
= $16.39

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
