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

End date: December 16, 2024

a = 2.3998

b = 0.0008

s = 0.0649

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 33.00%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0649) – 1
= 29.66%

May 9, 2022 calculations

Top border of price channel:

Exp(Y359)
= Exp(a + b × X359 + 2 × s)
= Exp(a + b × 522 + 2 × s)
= Exp(2.3998 + 0.0008 × 522 + 2 × 0.0649)
= Exp(2.9376)
= $18.87

Bottom border of price channel:

Exp(Y359)
= Exp(a + b × X359 – 2 × s)
= Exp(a + b × 522 – 2 × s)
= Exp(2.3998 + 0.0008 × 522 – 2 × 0.0649)
= Exp(2.6778)
= $14.55

December 16, 2024 calculations

Top border of price channel:

Exp(Y1,014)
= Exp(a + b × X1,014 + 2 × s)
= Exp(a + b × 1,474 + 2 × s)
= Exp(2.3998 + 0.0008 × 1,474 + 2 × 0.0649)
= Exp(3.6815)
= $39.71

Bottom border of price channel:

Exp(Y1,014)
= Exp(a + b × X1,014 – 2 × s)
= Exp(a + b × 1,474 – 2 × s)
= Exp(2.3998 + 0.0008 × 1,474 – 2 × 0.0649)
= Exp(3.4217)
= $30.62

a = 3.1563

b = 0.0002

s = 0.0464

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0002) – 1
= 8.15%

Price channel spread:

Exp(4 × s) – 1
