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 PG 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 20, 2024
End date: September 17, 2025

a = 5.4238

b = -0.0002

s = 0.0249

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -7.09%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0249) – 1
= 10.49%

Top border of price channel:

Exp(Y985)
= Exp(a + b × X985 + 2 × s)
= Exp(a + b × 1,432 + 2 × s)
= Exp(5.4238 + -0.0002 × 1,432 + 2 × 0.0249)
= Exp(5.1850)
= $178.57

Bottom border of price channel:

Exp(Y985)
= Exp(a + b × X985 – 2 × s)
= Exp(a + b × 1,432 – 2 × s)
= Exp(5.4238 + -0.0002 × 1,432 – 2 × 0.0249)
= Exp(5.0853)
= $161.62
