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


Primary Trend

Start date: September 26, 2023
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

= Exp(a + b × 1,811 + 2 × s)
= Exp(3.5449 + 0.0007 × 1,811 + 2 × 0.0311)
= Exp(4.9043)
= $134.86

Bottom border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,811 – 2 × s)
