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 DTE 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

End date: November 5, 2024
a = 3.5449
b = 0.0007
s = 0.0311
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 29.88%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0311) – 1
= 13.26%

Top border of price channel:
Exp(Y966)
= Exp(a + b × X966 + 2 × s)
= Exp(a + b × 1,405 + 2 × s)
= Exp(3.5449 + 0.0007 × 1,405 + 2 × 0.0311)
= Exp(4.6135)
= $100.83
Bottom border of price channel:
Exp(Y966)
= Exp(a + b × X966 – 2 × s)
= Exp(a + b × 1,405 – 2 × s)
= Exp(3.5449 + 0.0007 × 1,405 – 2 × 0.0311)
= Exp(4.4889)
= $89.03

Bottom border of price channel:
Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,811 – 2 × s)
