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 GVA 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 7, 2023
End date: November 19, 2024

a = 0.8755

b = 0.0020

s = 0.0600

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1
= 104.79%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0600) – 1
= 27.15%

September 7, 2023 calculations

Top border of price channel:

Exp(Y954)
= Exp(a + b × X954 + 2 × s)
= Exp(a + b × 1,387 + 2 × s)
= Exp(0.8755 + 0.0020 × 1,387 + 2 × 0.0600)
= Exp(3.7195)
= $41.24

Bottom border of price channel:

Exp(Y954)
= Exp(a + b × X954 – 2 × s)
= Exp(a + b × 1,387 – 2 × s)
= Exp(0.8755 + 0.0020 × 1,387 – 2 × 0.0600)
= Exp(3.4793)
= $32.44

= Exp(4.5817)
= $97.68

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
