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 CPRT 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: April 22, 2022
End date: May 24, 2024

a = 2.3275

b = 0.0010

s = 0.0625

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 46.60%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0625) – 1
= 28.41%

Top border of price channel:

Exp(Y609)
= Exp(a + b × X609 + 2 × s)
= Exp(a + b × 884 + 2 × s)
= Exp(2.3275 + 0.0010 × 884 + 2 × 0.0625)
= Exp(3.3790)
= $29.34

Bottom border of price channel:

Exp(Y609)
= Exp(a + b × X609 – 2 × s)
= Exp(a + b × 884 – 2 × s)
= Exp(2.3275 + 0.0010 × 884 – 2 × 0.0625)
= Exp(3.1289)
= $22.85

Top border of price channel:

Exp(Y1,134)
= Exp(a + b × X1,134 + 2 × s)
= Exp(a + b × 1,647 + 2 × s)
= Exp(2.3275 + 0.0010 × 1,647 + 2 × 0.0625)
= Exp(4.1786)
= $65.28

Bottom border of price channel:

Exp(Y1,134)
= Exp(a + b × X1,134 – 2 × s)
= Exp(a + b × 1,647 – 2 × s)
= Exp(2.3275 + 0.0010 × 1,647 – 2 × 0.0625)
= Exp(3.9286)
