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 LDOS 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: March 8, 2023
End date: December 9, 2024

a = 2.9706

b = 0.0013

s = 0.0648

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0013) – 1
= 60.82%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0648) – 1
= 29.61%

March 8, 2023 calculations

Top border of price channel:

Exp(Y721)
= Exp(a + b × X721 + 2 × s)
= Exp(a + b × 1,045 + 2 × s)
= Exp(2.9706 + 0.0013 × 1,045 + 2 × 0.0648)
= Exp(4.4606)
= $86.54

Bottom border of price channel:

Exp(Y721)
= Exp(a + b × X721 – 2 × s)
= Exp(a + b × 1,045 – 2 × s)
= Exp(2.9706 + 0.0013 × 1,045 – 2 × 0.0648)
= Exp(4.2012)
= $66.76

Top border of price channel:

Exp(Y1,163)
= Exp(a + b × X1,163 + 2 × s)
= Exp(a + b × 1,687 + 2 × s)
= Exp(2.9706 + 0.0013 × 1,687 + 2 × 0.0648)
= Exp(5.2962)
= $199.58

Bottom border of price channel:

Exp(Y1,163)
= Exp(a + b × X1,163 – 2 × s)
= Exp(a + b × 1,687 – 2 × s)
= Exp(2.9706 + 0.0013 × 1,687 – 2 × 0.0648)
= Exp(5.0368)
