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 AVA 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 15, 2023
End date: April 28, 2025

a = 2.8821

b = 0.0004

s = 0.0402

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0004) – 1
= 17.40%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0402) – 1
= 17.44%

August 15, 2023 calculations

Top border of price channel:

Exp(Y829)
= Exp(a + b × X829 + 2 × s)
= Exp(a + b × 1,203 + 2 × s)
= Exp(2.8821 + 0.0004 × 1,203 + 2 × 0.0402)
= Exp(3.4911)
= $32.82

Bottom border of price channel:

Exp(Y829)
= Exp(a + b × X829 – 2 × s)
= Exp(a + b × 1,203 – 2 × s)
= Exp(2.8821 + 0.0004 × 1,203 – 2 × 0.0402)
= Exp(3.3303)
= $27.95

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(2.8821 + 0.0004 × 1,825 + 2 × 0.0402)
= Exp(3.7644)
= $43.14

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(2.8821 + 0.0004 × 1,825 – 2 × 0.0402)
= Exp(3.6036)
= $36.73
