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 PAG 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: June 7, 2023
End date: November 20, 2024

a = 5.0438

b = 0.0000

s = 0.0461

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= -0.25%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0461) – 1
= 20.24%

Top border of price channel:

Exp(Y890)
= Exp(a + b × X890 + 2 × s)
= Exp(a + b × 1,294 + 2 × s)
= Exp(5.0438 + 0.0000 × 1,294 + 2 × 0.0461)
= Exp(5.1272)
= $168.54

Bottom border of price channel:

Exp(Y890)
= Exp(a + b × X890 – 2 × s)
= Exp(a + b × 1,294 – 2 × s)
= Exp(5.0438 + 0.0000 × 1,294 – 2 × 0.0461)
= Exp(4.9429)
= $140.17

= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(5.0438 + 0.0000 × 1,826 + 2 × 0.0461)
= Exp(5.1236)
= $167.94

Bottom border of price channel:

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