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 30, 2022
End date: December 27, 2024

a = 4.5481

b = 0.0003

s = 0.0368

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 13.55%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0368) – 1
= 15.87%

August 30, 2022 calculations

Top border of price channel:

Exp(Y608)
= Exp(a + b × X608 + 2 × s)
= Exp(a + b × 881 + 2 × s)
= Exp(4.5481 + 0.0003 × 881 + 2 × 0.0368)
= Exp(4.9283)
= $138.15

Bottom border of price channel:

Exp(Y608)
= Exp(a + b × X608 – 2 × s)
= Exp(a + b × 881 – 2 × s)
= Exp(4.5481 + 0.0003 × 881 – 2 × 0.0368)
= Exp(4.7810)
= $119.23

Top border of price channel:

Exp(Y1,193)
= Exp(a + b × X1,193 + 2 × s)
= Exp(a + b × 1,731 + 2 × s)
= Exp(4.5481 + 0.0003 × 1,731 + 2 × 0.0368)
= Exp(5.2241)
= $185.70

Bottom border of price channel:

Exp(Y1,193)
= Exp(a + b × X1,193 – 2 × s)
= Exp(a + b × 1,731 – 2 × s)
= Exp(4.5481 + 0.0003 × 1,731 – 2 × 0.0368)
= Exp(5.0769)
= $160.27
