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 CASY 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 17, 2023
End date: November 20, 2024

a = 4.0539

b = 0.0011

s = 0.0383

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 47.70%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0383) – 1
= 16.58%

Top border of price channel:

Exp(Y815)
= Exp(a + b × X815 + 2 × s)
= Exp(a + b × 1,184 + 2 × s)
= Exp(4.0539 + 0.0011 × 1,184 + 2 × 0.0383)
= Exp(5.3958)
= $220.48

Bottom border of price channel:

Exp(Y815)
= Exp(a + b × X815 – 2 × s)
= Exp(a + b × 1,184 – 2 × s)
= Exp(4.0539 + 0.0011 × 1,184 – 2 × 0.0383)
= Exp(5.2424)
= $189.12
