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 THRM 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 29, 2021
End date: March 28, 2025
a = 4.7250
b = -0.0006
s = 0.1028
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0006) – 1
= -19.34%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1028) – 1
= 50.89%

Top border of price channel:
Exp(Y315)
= Exp(a + b × X315 + 2 × s)
= Exp(a + b × 456 + 2 × s)
= Exp(4.7250 + -0.0006 × 456 + 2 × 0.1028)
= Exp(4.6621)
= $105.86
Bottom border of price channel:
Exp(Y315)
= Exp(a + b × X315 – 2 × s)
= Exp(a + b × 456 – 2 × s)
= Exp(4.7250 + -0.0006 × 456 – 2 × 0.1028)
= Exp(4.2508)
= $70.16

Top border of price channel:
Exp(Y1,235)
= Exp(a + b × X1,235 + 2 × s)
= Exp(a + b × 1,794 + 2 × s)
= Exp(4.7250 + -0.0006 × 1,794 + 2 × 0.1028)
= Exp(3.8741)
= $48.14
Bottom border of price channel:
Exp(Y1,235)
= Exp(a + b × X1,235 – 2 × s)
= Exp(a + b × 1,794 – 2 × s)
= Exp(4.7250 + -0.0006 × 1,794 – 2 × 0.1028)
= Exp(3.4627)
= $31.90
