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 RDN 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: September 21, 2022
End date: July 25, 2024

a = 1.8342

b = 0.0009

s = 0.0529

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 39.82%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0529) – 1
= 23.57%

September 21, 2022 calculations

Top border of price channel:

Exp(Y795)
= Exp(a + b × X795 + 2 × s)
= Exp(a + b × 1,153 + 2 × s)
= Exp(1.8342 + 0.0009 × 1,153 + 2 × 0.0529)
= Exp(2.9989)
= $20.06

Bottom border of price channel:

Exp(Y795)
= Exp(a + b × X795 – 2 × s)
= Exp(a + b × 1,153 – 2 × s)
= Exp(1.8342 + 0.0009 × 1,153 – 2 × 0.0529)
= Exp(2.7873)
= $16.24

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(1.8342 + 0.0009 × 1,826 + 2 × 0.0529)
= Exp(3.6170)
= $37.22

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
= Exp(1.8342 + 0.0009 × 1,826 – 2 × 0.0529)
= Exp(3.4053)
= $30.12
