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 MPC 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: August 4, 2023
End date: September 4, 2025

a = 4.9863

b = 0.0000

s = 0.1042

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 1.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1042) – 1
= 51.74%

Top border of price channel:

Exp(Y673)
= Exp(a + b × X673 + 2 × s)
= Exp(a + b × 977 + 2 × s)
= Exp(4.9863 + 0.0000 × 977 + 2 × 0.1042)
= Exp(5.2369)
= $188.10

Bottom border of price channel:

Exp(Y673)
= Exp(a + b × X673 – 2 × s)
= Exp(a + b × 977 – 2 × s)
= Exp(4.9863 + 0.0000 × 977 – 2 × 0.1042)
= Exp(4.8200)
= $123.96

Top border of price channel:

Exp(Y1,195)
= Exp(a + b × X1,195 + 2 × s)
= Exp(a + b × 1,739 + 2 × s)
= Exp(4.9863 + 0.0000 × 1,739 + 2 × 0.1042)
= Exp(5.2698)
= $194.38

Bottom border of price channel:

Exp(Y1,195)
= Exp(a + b × X1,195 – 2 × s)
= Exp(a + b × 1,739 – 2 × s)
= Exp(4.9863 + 0.0000 × 1,739 – 2 × 0.1042)
= Exp(4.8528)
= $128.10
