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 TRGP 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: November 7, 2023
End date: February 21, 2025

a = 1.4416

b = 0.0022

s = 0.0532

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0022) – 1
= 123.28%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0532) – 1
= 23.73%

Top border of price channel:

Exp(Y905)
= Exp(a + b × X905 + 2 × s)
= Exp(a + b × 1,313 + 2 × s)
= Exp(1.4416 + 0.0022 × 1,313 + 2 × 0.0532)
= Exp(4.4377)
= $84.58

Bottom border of price channel:

Exp(Y905)
= Exp(a + b × X905 – 2 × s)
= Exp(a + b × 1,313 – 2 × s)
= Exp(1.4416 + 0.0022 × 1,313 – 2 × 0.0532)
= Exp(4.2247)
= $68.36

February 21, 2025 calculations

Top border of price channel:

Exp(Y1,227)
= Exp(a + b × X1,227 + 2 × s)
= Exp(a + b × 1,785 + 2 × s)
= Exp(1.4416 + 0.0022 × 1,785 + 2 × 0.0532)
= Exp(5.4764)
= $239.00

Bottom border of price channel:

Exp(Y1,227)
= Exp(a + b × X1,227 – 2 × s)
= Exp(a + b × 1,785 – 2 × s)
= Exp(1.4416 + 0.0022 × 1,785 – 2 × 0.0532)
= Exp(5.2635)
= $193.16
