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 RGR 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: November 11, 2025
End date: March 13, 2026

a = -0.5238

b = 0.0023

s = 0.0389

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0023) – 1
= 132.46%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0389) – 1
= 16.86%

Top border of price channel:

Exp(Y1,171)
= Exp(a + b × X1,171 + 2 × s)
= Exp(a + b × 1,701 + 2 × s)
= Exp(-0.5238 + 0.0023 × 1,701 + 2 × 0.0389)
= Exp(3.4854)
= $32.63

Bottom border of price channel:

Exp(Y1,171)
= Exp(a + b × X1,171 – 2 × s)
= Exp(a + b × 1,701 – 2 × s)
