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 PIPR 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: April 3, 2025
End date: August 27, 2025

a = 0.3362

b = 0.0030

s = 0.0355

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0030) – 1
= 199.92%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0355) – 1
= 15.24%

Top border of price channel:

Exp(Y1,154)
= Exp(a + b × X1,154 + 2 × s)
= Exp(a + b × 1,679 + 2 × s)
= Exp(0.3362 + 0.0030 × 1,679 + 2 × 0.0355)
= Exp(5.4595)
= $234.99

Bottom border of price channel:

Exp(Y1,154)
= Exp(a + b × X1,154 – 2 × s)
= Exp(a + b × 1,679 – 2 × s)
= Exp(0.3362 + 0.0030 × 1,679 – 2 × 0.0355)
= Exp(5.3177)
= $203.91
