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 PRA 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: June 10, 2024
End date: October 23, 2025
a = 0.2725
b = 0.0017
s = 0.0998
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0017) – 1
= 83.04%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0998) – 1
= 49.05%

Top border of price channel:
Exp(Y910)
= Exp(a + b × X910 + 2 × s)
= Exp(a + b × 1,323 + 2 × s)
= Exp(0.2725 + 0.0017 × 1,323 + 2 × 0.0998)
= Exp(2.6633)
= $14.34
Bottom border of price channel:
Exp(Y910)
= Exp(a + b × X910 – 2 × s)
= Exp(a + b × 1,323 – 2 × s)
= Exp(0.2725 + 0.0017 × 1,323 – 2 × 0.0998)
= Exp(2.2642)
= $9.62
