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 BLFS 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 10, 2023
End date: July 26, 2024

a = -0.4803

b = 0.0020

s = 0.1040

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0020) – 1
= 105.33%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1040) – 1
= 51.56%

Top border of price channel:

Exp(Y1,016)
= Exp(a + b × X1,016 + 2 × s)
= Exp(a + b × 1,473 + 2 × s)
= Exp(-0.4803 + 0.0020 × 1,473 + 2 × 0.1040)
= Exp(2.6311)
= $13.89

Bottom border of price channel:

Exp(Y1,016)
= Exp(a + b × X1,016 – 2 × s)
= Exp(a + b × 1,473 – 2 × s)
= Exp(-0.4803 + 0.0020 × 1,473 – 2 × 0.1040)
= Exp(2.2152)
= $9.16

= Exp(-0.4803 + 0.0020 × 1,824 + 2 × 0.1040)
= Exp(3.3229)
= $27.74

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
